XWPFTableCell is a IBody. So it provides XWPFTable insertNewTbl(org.apache.xmlbeans.XmlCursor cursor). So yes, it is possible to add a table into a table cell.
But the usage of that org.apache.xmlbeans.XmlCursor is not well documented.
To create that cursor we need the table cell, the cursor shall be in, and an new empty paragrsph in that cell. The empty paragrsph is needed because all content we insert using that cursor will be before the element the cursor points to. So that element should be an empty paragraph to avoid inserting content into existing elements like paragraphs with content or other content containing elements.
The following shows the simplest possible complete example.
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;
public class CreateWordTableInTable {
public static void main(String[] args) throws Exception {
try (XWPFDocument doc = new XWPFDocument()) {
//create main table
XWPFTable table = doc.createTable();
//create rows and cells
XWPFTableRow row = table.getRow(0);
row.getCell(0).setText("Main table A1");
row.addNewTableCell().setText("Main table B1");
row.addNewTableCell().setText("Main table C1");
row = table.createRow();
row.getCell(0).setText("Main table A2");
row.getCell(1).setText("Main table B2");
row.getCell(2).setText("Main table C2");
//create inner table
//we need the first table cell and an new empty paragrsph in that first cell
row = table.getRow(0);
XWPFTableCell cell = row.getTableCells().get(0);
XWPFParagraph paragraph = cell.addParagraph();
//now we can insert a table there
org.apache.xmlbeans.XmlCursor cursor = paragraph.getCTP().newCursor();
XWPFTable innerTable = cell.insertNewTbl(cursor);
//set table borders
innerTable.setTopBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
innerTable.setRightBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
innerTable.setBottomBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
innerTable.setLeftBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
innerTable.setInsideHBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
innerTable.setInsideVBorder(XWPFTable.XWPFBorderType.SINGLE, 4, 0, "000000");
//create rows and cells
XWPFTableRow rowInInnerTable = innerTable.createRow();
XWPFTableCell cellInInnerTable = rowInInnerTable.createCell();
cellInInnerTable.setText("Inner table A1");
cellInInnerTable = rowInInnerTable.createCell();
cellInInnerTable.setText("Inner table B1");
cellInInnerTable = rowInInnerTable.createCell();
cellInInnerTable.setText("Inner table C1");
rowInInnerTable = innerTable.createRow();
cellInInnerTable = rowInInnerTable.getCell(0);
cellInInnerTable.setText("Inner table A2");
cellInInnerTable = rowInInnerTable.getCell(1);
cellInInnerTable.setText("Inner table B2");
cellInInnerTable = rowInInnerTable.getCell(2);
cellInInnerTable.setText("Inner table C2");
//save to .docx file

How to get datavalidation source for a cell in java using poi?

I have defined a list of valuses my_list in one excel sheet as follow:
In another excel sheet, I reference for some cells to that list sothat this list is shown as dropdown in the cell as follows:
Using poi, I go throw excel sheet rows/columns and read cells for cell.
I get value of cells using method:
cell.getStringCellValue()
My question is how to get the name of the list my_list from the cell?

This problem contains multiple different problems.
First we need get sheet's data validations and then for each data validation get Excel cell ranges the data validation applies to. If the cell is in one of that cell ranges and if data validation is a list constraint then do further proceedings. Else return a default value.
If we have a explicit list like "item1, item2, item3, ..." then return this.
Else if we have a formula creating the list and is formula1 a area reference to a range in same sheet, then get all cells in that cell range and put their values in an array and return this.
Else if we have a formula creating the list and is formula1 a reference to a defined name in Excel, then get the Excel cell range the name refers to. Get all cells in that cell range and put their values in an array and return this.
Complete Example. The ExcelWorkbook contains the data validation in first sheet cell D1.

String[] listValues = new String[cellReferences.length]; // and put their values in an array
for (int i = 0 ; i < cellReferences.length; i++) {
CellReference cellReference = cellReferences[i];
if (cellReference.getSheetName() == null) {
listValues[i] = dataFormatter.formatCellValue(
sheet.getRow(cellReference.getRow()).getCell(cellReference.getCol())

String[] dataValidationListValues = getDataValidationListValues(sheet, cell);
for (String dataValidationListValue : dataValidationListValues) {
System.out.println(dataValidationListValue);
}
workbook.close();
}
}
Note: Current Excel versions allow data validation list reference to be a direct area reference to another sheet without using a named range. But this is nothing what apache poi can get. Apache poi is on Excel 2007 level only.

The my_list your mean is Define Name in excel, honestly i don't know is apache-poi can do it or not. But this is may a clue, you can get the my_list formula using .getRefersToFormula();, please try the bellow code :
String defineNameFromExcel = "my_list";
List define = new ArrayList<>();
define = myExcel.getAllNames();
Iterator<List> definedNameIter = define.iterator();
while(definedNameIter.hasNext()) {
Name name = (Name) definedNameIter.next();
if(name.getNameName().equals(defineNameFromExcel)) {
String sheetName = name.getSheetName();
String range = name.getRefersToFormula();
range = range.substring(range.lastIndexOf("!"));
System.out.println(sheetName);
System.out.println(range);
}
}
It will get sheet name and range, with the information may you can extract for get the value you want, hope this helps.

why apache poi reading less number of cell in a row of excel

I am trying to fetch the cell using named range.But After trying the below code,not able to get consistent cell in a row of the sheet that's getting null exception while using r.getCell().
String cname = "TestName";
Workbook wb = getMyWorkbook(); // retrieve workbook
// retrieve the named range
int namedCellIdx = wb.getNameIndex(cellName);
Name aNamedCell = wb.getNameAt(namedCellIdx);
// retrieve the cell at the named range and test its contents
AreaReference aref = new AreaReference(aNamedCell.getRefersToFormula());
CellReference[] crefs = aref.getAllReferencedCells();
for (int i = 0; i < crefs.length; i++) {
Sheet s = wb.getSheet(crefs[i].getSheetName());
Row r = sheet.getRow(crefs[i].getRow());
Cell c = r.getCell(crefs[i].getCol());
// extract the cell contents based on cell type etc.
}

For the sake of memory consuming, totally empty rows are not stored on the sheet. Also totally empty cells are not stored in rows of the sheet.
Sheet.getRow returns null if the row is not defined on the sheet. Also Row.getCell returns null if the cell is undefined in that row.
So we always need check:
...
Row r = sheet.getRow(crefs[i].getRow());
if (r == null) {
//row is empty
} else {
Cell c = r.getCell(crefs[i].getCol());
if (c == null) {
//cell is empty
} else {
//do something with c
}
}
...

Apache POI - How to copy tables from one docx to another docx

Hi I am trying to copy a table from a docx file to another but what happens is that the value of the table are copied down bellow the table in the new document and outside of it (see pictures bellow)
Table in original docx
Talbe in the new docx
As you can see the values of the table are copied outside the table.
I am using Libre Office, apache poi version 3.17 and my computer runs Ubuntu 16.04
The code I am using to perform the copy is the following
public static void copyTable(XWPFDocument input_doc,XWPFDocument output_doc,
int table_index_input, int table_index_output) {
XWPFTable template_table = input_doc.getTables().get(table_index_input);
CTTbl ctTbl = CTTbl.Factory.newInstance(); // Create a new CTTbl for the new table
ctTbl.set(template_table.getCTTbl()); // Copy the template table's CTTbl
XWPFTable new_table = new XWPFTable(ctTbl, output_doc); // Create a new table using the CTTbl upon
output_doc.createParagraph();
output_doc.createTable();// Create a empty table in the document
output_doc.setTable(table_index_output, new_table); // Replace the empty table to table2
}

XWPFTable newTbl = output_doc.insertNewTbl(cursor);
copyTable(table, newTbl);
and the copyTable() method
private void copyTable(XWPFTable source, XWPFTable target) {
target.getCTTbl().setTblPr(source.getCTTbl().getTblPr());
target.getCTTbl().setTblGrid(source.getCTTbl().getTblGrid());
for (int r = 0; r<source.getRows().size(); r++) {
XWPFTableRow targetRow = target.createRow();
XWPFTableRow row = source.getRows().get(r);
targetRow.getCtRow().setTrPr(row.getCtRow().getTrPr());
for (int c=0; c<row.getTableCells().size(); c++) {
//newly created row has 1 cell
XWPFTableCell targetCell = c==0 ? targetRow.getTableCells().get(0) : targetRow.createCell();
XWPFTableCell cell = row.getTableCells().get(c);
targetCell.getCTTc().setTcPr(cell.getCTTc().getTcPr());
XmlCursor cursor = targetCell.getParagraphArray(0).getCTP().newCursor();
for (int p = 0; p < cell.getBodyElements().size(); p++) {
IBodyElement elem = cell.getBodyElements().get(p);
if (elem instanceof XWPFParagraph) {
XWPFParagraph targetPar = targetCell.insertNewParagraph(cursor);
cursor.toNextToken();
XWPFParagraph par = (XWPFParagraph) elem;
copyParagraph(par, targetPar);
} else if (elem instanceof XWPFTable) {
XWPFTable targetTable = targetCell.insertNewTbl(cursor);
XWPFTable table = (XWPFTable) elem;
copyTable(table, targetTable);
cursor.toNextToken();
}
}
//newly created cell has one default paragraph we need to remove
targetCell.removeParagraph(targetCell.getParagraphs().size()-1);
}
}
//newly created table has one row by default. we need to remove the default row.
target.removeRow(0);
}
the copyParagraph()
private void copyParagraph(XWPFParagraph source, XWPFParagraph target) {
target.getCTP().setPPr(source.getCTP().getPPr());
for (int i=0; i<source.getRuns().size(); i++ ) {
XWPFRun run = source.getRuns().get(i);
XWPFRun targetRun = target.createRun();
//copy formatting
targetRun.getCTR().setRPr(run.getCTR().getRPr());
//no images just copy text
targetRun.setText(run.getText(0));
}
}

I think easier and more reliable form of copyTable function would be something like this.
private void copyTable(XWPFTable source, XWPFTable target) {
CTTbl sourceCTTbl = source.getCTTbl();
CTTbl targetCTTbl = target.getCTTbl();
targetCTTbl.setTblPr(sourceCTTbl.getTblPr());
targetCTTbl.setTrArray(sourceCTTbl.getTrArray());
}
(It works for me at least)

Retrieve values from excel using poi

I am trying to get the column values for a specific row in a excel using poi methods.
I am able to get the values but the problem is I want the values only from second column.
public static ArrayList<String> GetBusinessComponentList() throws IOException{
String Tcname = "TC02_AggregateAutoByPassRO_CT";
ArrayList<String> arrayListBusinessFlow ;
arrayListBusinessFlow = new ArrayList<String>();
FileInputStream fileInput = new FileInputStream(oFile);
wb = new HSSFWorkbook(fileInput);
sheet = wb.getSheet("Business Flow");
int rownr = findRow(sheet, Tcname);
row = sheet.getRow(rownr);
for (Cell cell : row) {
String arr = cell.getStringCellValue();
arrayListBusinessFlow.add(arr);
}
return arrayListBusinessFlow;
}
private static int findRow(HSSFSheet sheet, String cellContent){
for (Row row : sheet) {
for (Cell cell : row) {
if (cell.getCellType() == Cell.CELL_TYPE_STRING) {
if (cell.getRichStringCellValue().getString().trim().equals(cellContent)) {
return row.getRowNum();
}
}
}
}
return 0;
}
}
OUTPUT:
[TC02_AggregateAutoByPassRO_CT,
StrategicUINewBusiness.Login,
StrategicUINewBusiness.CustomerSearch,
StrategicUINewBusiness.NamedInsured,
StrategicUINewBusiness.InsuranceScoreByPass,

But I do not want my test case name when I am getting.
Please help me what changes i needed to do. thanks!

Currently, the code you're using to iterate over cells only returns cells with content or styling, and skips totally empty ones. You need to change to one of the other ways of iterating over cells, so you can control it to read from the second column onwards.
If you look at the Apache POI Documentation on iterating over rows and cells, you'll see a lot more details on the two main ways to iterate.
For your case, you'll want something like:
// We want to read from the 2nd column onwards, zero based
int firstColumn = 1;
// Always fetch at least 4 columns
int MY_MINIMUM_COLUMN_COUNT = 5;
// Work out the last column to go to
int lastColumn = Math.max(r.getLastCellNum(), MY_MINIMUM_COLUMN_COUNT);
// To format cells into strings
DataFormatter df = new DataFormatter();
// Iterate over the cells
for (int cn = firstColumn; cn < lastColumn; cn++) {
Cell c = r.getCell(cn, Row.RETURN_BLANK_AS_NULL);
if (c == null) {
// The spreadsheet is empty in this cell
} else {
// Do something useful with the cell's contents
// eg get the cells value as a string
String cellAsString = df.formatCellValue(c);
}
}

Use Cell cell=row.getCell(1); and also you can use sheet.getLastRowNum() to get the number last row on the sheet.
for (int i=0;i<=row.getLastCellNum();i++) {
if (i!=1){
//your stuff
}
}
