Apache poi cell diagonal strikethrough

How can I strikethrough diagonally a cell in excel using Apache poi?
I want to get something like this:
I have tried:
cell.getCellStyle().setFillPattern(CellStyle.THIN_BACKWARD_DIAG)
but then the cell is having many diagonal lines instead of one from top right to bottom left.
Edit:
This is how I create the workbook:
Workbook workbook = new SXSSFWorkbook(SXSSFWorkbook.DEFAULT_WINDOW_SIZE);
Sheet sheet = workbook.createSheet("Test");
Then creating the columns and the rows, I don't see there any special to show.
Any idea what can I do?

Sorry for my previous answer, currently there is no diagonal border available readily in apache poi, though we can write our own custom method. You can use below method which will add a diagonal border in a cell.
public static void setDiagonal(StylesTable stylesSource, CTXf cellXtraFormating, ThemesTable theme) {
CTBorder ct = CTBorder.Factory.newInstance();
CTBorderPr pr = ct.addNewDiagonal();
ct.setDiagonalUp(true);
pr.setStyle(STBorderStyle.Enum.forInt(BorderFormatting.BORDER_THIN + 1));
int idx = stylesSource.putBorder(new XSSFCellBorder(ct, theme));
cellXtraFormating.setBorderId(idx);
cellXtraFormating.setApplyBorder(true);
}
call the above method in your class like this
CellStyle cs = workbook.createCellStyle();
StylesTable styleSource = ((XSSFWorkbook) workbook).getStylesSource();
ThemesTable theme = styleSource.getTheme();
CTXf cellXtraFormating = ((XSSFCellStyle) cs).getCoreXf();
-------your custom code---------
setDiagonal(styleSource, cellXtraFormating, theme);
cell.setCellStyle(cs);
I hope this answers your question

Reading from a word document using java

I'm trying to read data from a docx file using java. The data is is tables. Is there a way to iterate through the table cells and extract the cell data?

You have two choices:
Write a library that can open, read, and manipulate Word documents, for some definitions of "open", "read", and "manipulate", and some definition of "Word document".
Find a third-party library that can do some or all of what is defined in (1).
Search "java docx library" in your favourite web search and see what comes up.

This should help you.

Merge and align center cell using apache poi

I want to export data to excel using Apache poi. Now the problem that I am facing is that I am unable to merge rows and align them in the center.
Code for export data is:
List<LinkedHashMap<String,Object>> lstReportHeader = null;
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
//Set Header Font
HSSFFont headerFont = wb.createFont();
headerFont.setBoldweight(headerFont.BOLDWEIGHT_BOLD);
headerFont.setFontHeightInPoints((short) 12);
//Set Header Style
CellStyle headerStyle = wb.createCellStyle();
headerStyle.setFillBackgroundColor(IndexedColors.BLACK.getIndex());
headerStyle.setAlignment(headerStyle.ALIGN_CENTER);
headerStyle.setFont(headerFont);
headerStyle.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);
int rowCount= 0;
Row header;
header = sheet.createRow(0);//its for header
Cell cell ;//= header.createCell(0);
for(int j = 0;j < 4; j++) {
cell = header.createCell(j);
if(j == 0) {
cell.setCellValue("ItemWise List");
}
cell.setCellStyle(headerStyle);
}
sheet.addMergedRegion(new CellRangeAddress(rowCount, rowCount, 0, lstReportFormHeader.size()-1));
header = sheet.createRow(0);
cell = header.createCell(0);
cell.setCellValue("Sr. No");
cell = header.createCell(1);
cell.setCellValue("Item Name");
cell = header.createCell(2);
cell.setCellValue("Qty");
cell = header.createCell(3);
cell.setCellValue("Rate");
Now I want to ItemWise List merge and make it align center.

My solution was to merge the cells by their positions, then created a cell (reference to the first block of the merged cells) to assign a value and then set the alignment throught the CellUtil
// Merges the cells
CellRangeAddress cellRangeAddress = new CellRangeAddress(start, start, j, j + 1);
sheet.addMergedRegion(cellRangeAddress);
// Creates the cell
Cell cell = CellUtil.createCell(row, j, entry.getKey());
// Sets the allignment to the created cell
CellUtil.setAlignment(cell, workbook, CellStyle.ALIGN_CENTER);

Merge like:::
Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("new sheet");
Row row = sheet.createRow((short) 1);
Cell cell = row.createCell((short) 1);
cell.setCellValue("This is a test of merging");
sheet.addMergedRegion(new CellRangeAddress(
1, //first row (0-based)
1, //last row (0-based)
1, //first column (0-based)
2 //last column (0-based)
));
// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
For aligning also check the below official link of Apache poi:::
http://poi.apache.org/spreadsheet/quick-guide.html#Alignment

After study I found that after merging 7 cells, merged cell id will be 0 so I applied following style to cell id 0 using following style.
headerStyle.setAlignment(headerStyle.ALIGN_CENTER);

This worked for me and I think it's cleaner:
/**
* Merge and center the cells specified by range
* #param startCell the first cell in the cells to be merged
* #param range the range of the cells to be merged
*/
private static void mergeAndCenter(Cell startCell, CellRangeAddress range) {
startCell.getSheet().addMergedRegion(range);
CellStyle style = startCell.getSheet().getWorkbook().createCellStyle();
style.setAlignment(CellStyle.ALIGN_CENTER);
style.setVerticalAlignment(CellStyle.VERTICAL_CENTER);
startCell.setCellStyle(style);
}

As per my understanding, you have start and end cells for merging and you want to merge the cell ranges and align the cell content. If I am right, you can use the following method:
/**
* #param startCell: first cell of merging area
* #param endCell: last cell of merging area
*/
public static void mergeAndAlignCenter(HSSFCell startCell, HSSFCell endCell){
//finding reference of start and end cell; will result like $A$1
CellReference startCellRef= new CellReference(startCell.getRowIndex(),startCell.getColumnIndex());
CellReference endCellRef = new CellReference(endCell.getRowIndex(),endCell.getColumnIndex());
// forming string of references; will result like $A$1:$B$5
String cellRefernce = startCellRef.formatAsString()+":"+endCellRef.formatAsString();
//removing $ to make cellRefernce like A1:B5
cellRefernce = cellRefernce.replace("$","");
//passing cellRefernce to make a region
CellRangeAddress region = CellRangeAddress.valueOf(cellRefernce);
//use region to merge; though other method like sheet.addMergedRegion(new CellRangeAddress(1,1,4,1));
// is also available, but facing some problem right now.
startCell.getRow().getSheet().addMergedRegion( region );
//setting alignment to center
CellUtil.setAlignment(startCell, wb, CellStyle.ALIGN_CENTER);
}

Well what worked for me is to set all the merged cells' Cellstyle to CENTER ALIGN. Whether you put the XSSFSheet.addMergedRegion() method before or after setting the cellstyle values to center don't matter.
private void insertXlsHeader(XSSFSheet sheet){
....
//first cell for row1
cell = row1.createCell(colstart);
cell.setCellType(org.apache.poi.ss.usermodel.Cell.CELL_TYPE_STRING);
cell.setCellValue("COURSES");
setHeaderCellStyle(sheet,cell);
//first cell for row2
cell = row2.createCell(colstart);
setHeaderCellStyle(sheet,cell);
//first cell for row3
cell = row3.createCell(colstart);
setHeaderCellStyle(sheet,cell);
//merged the first cells of rows 1 to 3
sheet.addMergedRegion(new CellRangeAddress(ROW1, ROW3, colstart, colstart));
...
}
private void setHeaderCellStyle(XSSFSheet sheet,org.apache.poi.ss.usermodel.Cell cell) {
CellStyle s = null;
s = sheet.getWorkbook().createCellStyle();
cell.setCellStyle(s);
Font f = sheet.getWorkbook().createFont();
f.setBoldweight(Font.BOLDWEIGHT_BOLD);
s.setBorderBottom(CellStyle.BORDER_THIN);
s.setBorderLeft(CellStyle.BORDER_THIN);
s.setBorderRight(CellStyle.BORDER_THIN);
s.setBorderTop(CellStyle.BORDER_THIN);
s.setVerticalAlignment(CellStyle.VERTICAL_CENTER);
s.setAlignment(CellStyle.ALIGN_CENTER);
s.setFont(f);
}

As answered above, merging cells can be achieved using
sheet.addMergedRegion(new CellRangeAddress(frstRow, lastRow, firstColumnIndex, lastColumnIndex));
But for aligning cells vertically,recently I faced similar issue and I tried above answer, but using
CellUtil.setAlignment(dataCell, workbook, CellStyle.VERTICAL_CENTER);
aligned Date formatted cells to Horizontal Left aligned. So I used following method to set only Vertical Alignment of Cell content.
CellUtil.setCellStyleProperty(dataCell, workbook,CellUtil.VERTICAL_ALIGNMENT,CellStyle.VERTICAL_CENTER);
I hope this helps!!
Happy Coding

Use
style.setVerticalAlignment()
to set the vertical alignments instead of
style.setAlignment().

We can merge the column along with we can vertically and horizontally align too.
I had the rows 2 to 10 of column A having the same values.
I used the below code to merge the data where the variable sheet is XSSFSheet. The parameters of CellRangeAddress have the parameters are start row, last row, start column and last column. In my example, the value USA starts from 2nd row (index is 1) and the last value of USA is in 10th row and column is the 1st column.
CellRangeAddress ca = new CellRangeAddress(1,9,0,0);
sheet.addMergedRegion(ca);
When I executed the above code, the cell was merged but the text was not aligned to center.
To overcome this issue, I utilized the class CellStyle and Cell. Get the 2nd row of 1st column text to cell variable. Now set the vertical and horizontal alignment to the cellStyle and set this style to the cell which will align the text to the center.
Cell cell = sheet.getRow(1).getCell(0);
CellStyle cellStyle = workbook.createCellStyle();
cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);
cellStyle.setAlignment(HorizontalAlignment.CENTER);
cell.setCellStyle(cellStyle);
Below is the final result

Table creation on separate method using iText in Java

I'm trying to create an PDF document using iText. I followed to THIS nice tutorial and tried to create single page pdf document which has a table. In the tutorial the author keeps table creation of table on separate method such as addMetaData, addTitlePage and addContent. I also would keep them separately, but I'm new to iText and currently I'm stuck. The current code is:
public static void main(String args[]) {
try {
Document document = new Document(PageSize.A4);
PdfWriter.getInstance(document, new FileOutputStream(FILE));
document.open();
addMetaData(document);
addTitlePage(document);
addContent(document);
document.close();
} catch (Exception e) {
e.printStackTrace();
}
}
private static void addTitlePage(Document document) throws DocumentException {
Paragraph preface = new Paragraph();
// Add one empty line
addEmptyLine(preface, 1);
// Header of the document
preface.add(new Paragraph("Title here", capFont));
addEmptyLine(preface, 1);
// Report generated by: _name, _date
preface.add(new Paragraph("Report generated by: " + System.getProperty("user.name") + ", " + new Date(), //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$
normFont));
addEmptyLine(preface, 2);
preface.add(new Paragraph("This document describes some kind of price list which is unknown to me.", normFont));
document.add(preface);
}
private static void addContent(Document document) throws DocumentException {
Paragraph content = new Paragraph();
// Add one empty line
addEmptyLine(content, 1);
// Content of the document
content.add(new Paragraph(createTable(subPart), normFont)); // not working line
addEmptyLine(content, 5);
content.add(new Paragraph("This document is a preliminary version and not subject to the license agreement.", redFont));
document.add(content);
}
private static void createTable(Section subPart) throws BadElementException {
PdfPTable table = new PdfPTable(3);
table.setHorizontalAlignment(Element.ALIGN_CENTER);
// Data
table.addCell("1");
table.addCell("2");
table.addCell("3");
subPart.add(table);
}
Any help would be appreciated.

So, after one day literature reading and api homepage visiting I came to my solution:
Instead of: content.add(new Paragraph(createTable(subPart), normFont));
I have now: createTable(content);
and of course I changed the type of variable in createTable method to the paragraph in order to get it working.

iText TextField on a Landscape page - Input text not rotated

I'm generating a PDF using iText and wanted to include an iText Form and TextFields so that users can fill in the PDF Form electronically, rather than printing it out.
I've followed the Examples here: http://itextpdf.com/examples/iia.php?id=161
and here: http://itextpdf.com/examples/iia.php?id=162
So far, I have a TextField on my Landscape PDF, and I can click and enter text.
I have two issues:
TextField alignment. To click on the text field, I have to position my mouse to the right of the cell that I added the TextField too. How can I align the TextField with the cell?
Entered Text Rotation. Once I've entered text, it's displayed rotated and 90 degrees to the rest of the page. How can I set the rotation of this displayed text?
The rotation of the entered text is the thing that bugs me th most. I've tried setting the rotation on the cell and the TextField but that seems to have no effect.
Any suggestions?
Thanks
Here is my code:
int rotation = document.getPageSize().getRotation();
PdfFormField pdfForm = PdfFormField.createEmpty(docWriter);
coverSheetPdfForm.setFieldName("Form");
coverSheetPdfForm.setRotate(rotation);
...
cell = new PdfPCell(borderedTable("Cell Title:", tblHeadingFont, "", borderColor));
cell.setColspan(1);
cell.setPadding(5f);
cell.setBorderWidth(0f);
cell.setHorizontalAlignment(PdfPCell.ALIGN_LEFT);
cell.setMinimumHeight(100f);
TextField textField = new TextField(docWriter, new Rectangle(50, 50,rotation), "cell_text_field");
textField.setFontSize(12);
textField.setRotation(rotation);
textField.setVisibility(TextField.VISIBLE);
textField.setBorderColor(borderColor);
textField.setBorderWidth(BORDER_WIDTH);
cell.setCellEvent(new ChildFieldEvent(pdfForm, textField.getTextField(), 1, rotation));
.....
docWriter.addAnnotation(pdfForm);
and the ChildFieldEvent code that I've borrowed from the example page, and added a extra parameter for rotation:
/**
* Creates a ChildFieldEvent.
* #param parent the parent field
* #param kid the child field
* #param padding a padding
* #param rotation
*/
public ChildFieldEvent(PdfFormField parent, PdfFormField kid, float padding, int rotation) {
this.parent = parent;
this.kid = kid;
this.padding = padding;
this.rotation = rotation;
}
/**
* Add the child field to the parent, and sets the coordinates of the child field.
* #param cell
* #param rect
* #param cb
* #see com.lowagie.text.pdf.PdfPCellEvent#cellLayout(com.lowagie.text.pdf.PdfPCell,
* com.lowagie.text.Rectangle, com.lowagie.text.pdf.PdfContentByte[])
*/
#Override
public void cellLayout(PdfPCell cell, Rectangle rect, PdfContentByte[] cb) {
try {
parent.addKid(kid);
kid.setWidget(new Rectangle(rect.getLeft(padding), rect.getBottom(padding),
rect.getRight(padding), rect.getTop(padding),rotation),
PdfAnnotation.HIGHLIGHT_INVERT);
} catch (Exception e) {
throw new ExceptionConverter(e);
}
}

I've done some more testing and it looks like the Ubuntu PDF fiewer (Document Viewer) is not rendering the PDF correctly as viewing the same file in Windows Adobe PDF Viewer, the form looks fine.
I'll do more testing and report back.
