One Row in One Page: Boxable

This is the code for this issue for you to check if there is any problem in the code.
Now the problem is when I limit the rows to 45 (this number fits in one page) every row will print in one page.
But, If I don't limit the rows and the row size (approximately 100-200), every row goes to new page in the PDF. The PDF page number goes to approximately equal to row numbers.
I have opened this issue in Boxable's git but it's not active so I came for help here.
Following are the files generated in both conditions:

cell.setFontSize(fontSize);
cell.setBottomPadding(1);
}
}

I found a silly problem in my code. I am telling this so that someone else must not repeat this.
I treated every row of the data table as header row. So it went to new page.
To be specific. In the function drawTableData I removed table.addHeaderRow(sTableRow)

How to display Object array in JTable?

This is my code which I am using but when I am trying to print dataArray object, then data is not show in JTable. Which model properties of table to print Object array values can used and how?
public class ShowAddressForm extends javax.swing.JFrame {
Object data[][];
Object dataArray[][];
int count = 0;
String st;
public ShowAddressForm(String fname , String str) {
super(fname);
st = str;
initComponents();
fillTable();
}
public void fillTable()
{
int count = 0;
String str;
try
{
BufferedReader br = new BufferedReader(new FileReader("D:\\JavaPrograms\\Contact Management System\\InputFiles\\AddressFile"));
while((str = br.readLine()) != null)
{
count++;
}
br.close();
} catch (Exception e)
{
}
Object id;
Object name;
data = new Object[count][7];
int i = 0 , j = 0 , m;
try
{
BufferedReader buffrea = new BufferedReader(new FileReader("D:\\JavaPrograms\\Contact Management System\\InputFiles\\AddressFile"));
while((str = buffrea.readLine()) != null)
{
StringTokenizer token = new StringTokenizer(str , "*");
int n = token.countTokens();
id = token.nextElement();
name = token.nextElement();
String strNameLow = name.toString().toLowerCase();
String strNameUpp = name.toString().toUpperCase();
if(strNameLow.startsWith(st.toLowerCase()) || strNameUpp.startsWith(st.toUpperCase()))
{
data[i][0] = id;
data[i][1] = name;
for(j = 2 ; j < n ; j++)
{
data[i][j] = token.nextElement();
}
i = i + 1;
}
}
buffrea.close();
} catch(IOException ioe){
System.out.println("Error : " + ioe.toString());
}
dataArray = new Object[i][7];
for(int a = 0 ; a < i ; a++)
{
for(int b = 0 ; b < 7 ; b++)
{
dataArray[a][b] = data[a][b];
}
}
//Here is the code to print dataArray object which i used but it is not working, when i am run my program it is print "[Ljava.lang.Object;#1cc2e30" in table's first cell[0][0] position
DefaultTableModel model = (DefaultTableModel)this.data_table.getModel();
model.addRow(dataArray);
}

I filled data in a JTable like this. You might want to give it a try adapting it to your code. Variable and stuff are in spanish, just replace them with what you need. In my case it's a table with 4 columns representing a date, a score, duration and max viewers.
private void fillJTable(){
//creating data to add into the JTable. Here you might want to import your proper data from elsewhere
Date date = new Date();
UserReplay rep1 = new UserReplay(date, 12, 13,14);
UserReplay rep2 = new UserReplay(date, 2,34,5);
ArrayList<UserReplay> usuaris = new ArrayList<>();
usuaris.add(rep1);
usuaris.add(rep2);
//----Filling Jtable------
DefaultTableModel model = (DefaultTableModel) view.getTable().getModel();
model.addColumn("Fecha");
model.addColumn("Puntuación");
model.addColumn("Tiempo de duración");
model.addColumn("Pico máximo de espectadores");
for (int i = 0; i < usuaris.size(); i++){
Vector<Date> fecha = new Vector<>(Arrays.asList(usuaris.get(i).getDate()));
Vector<Integer> puntuacion = new Vector<>(Arrays.asList(usuaris.get(i).getPuntuacion()));
Vector<Integer> tiempo = new Vector<>(Arrays.asList(usuaris.get(i).getTiempo()));
Vector<Integer> espectadors = new Vector<>(Arrays.asList(usuaris.get(i).getTiempo()));
Vector<Object> row = new Vector<Object>();
row.addElement(fecha.get(0));
row.addElement(puntuacion.get(0));
row.addElement(tiempo.get(0));
row.addElement(espectadors.get(0));
model.addRow(row);
}
}

If what you want is to display the full text of the cells instead of an abbreviation, you can use the Table Column Adjuster. e.g.:
String[] columnNames = {"Colum1", "Colum2", "Colum2"};
String[][] data = {
{"ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-", "-"},
{"-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ", "-"},
{"-", "-", "ABCDEFGHIJKLMNOPQRSTUVWXYZ"}
};
TableModel model = new DefaultTableModel(data, columnNames);
JTable table = new JTable();
table.setModel(model);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
TableColumnAdjuster tca = new TableColumnAdjuster(table);
tca.adjustColumns();
JScrollPane pane = new JScrollPane(table);
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(pane);
frame.setSize(400, 300);
frame.setVisible(true);
You can get the code for the class TableColumnAdjuster from http://www.camick.com/java/source/TableColumnAdjuster.java

Found a way )
table.setModel(tableModel);
table = autoResizeColWidth(table, tableModel);
//table.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
SimpleDateFormat formatter = new SimpleDateFormat("yyyy/MM");
DatePickerCellEditor datePicker = new DatePickerCellEditor(formatter);
datePicker.setFormats(formatter);
date = table.getColumnModel().getColumn(18);
date.setCellEditor(datePicker);
table = new RXTable(tableModel) {
#Override
public boolean getScrollableTracksViewportWidth() {

}
};
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

//table.getColumnModel().getColumn(0).setMinWidth(100);
//table.getColumnModel().getColumn(1).setMinWidth(100);

Android: How to parse HTML Table into ListView?

Hello i want to parse a HTML Table into a Android ListView but i don't know where to start. The Table has a lot of information. Could someone help me to start with this?
Thanks in advance!
The HTML Table: http://intranet.staring.nl/toepassingen/rooster/lochem/2W2/2012090320120909/2W01533.htm (Just click view source).

You will first need to parse the HTML table into a data structure, and then use ListView to display that information. Try using the JSoup library to do the HTML parsing: http://jsoup.org/cookbook/introduction/parsing-a-document

I don't know if you already got your answer here but I did the same with the link you suggest, I will post my code here but it is still very messy and don't apply for the newest timetable(9th hour)
Im using HTML Cleaner library for parsing the html:
try {
HtmlCleaner hc = new HtmlCleaner();

cp.setAllowMultiWordAttributes(true);
cp.setRecognizeUnicodeChars(true);
cp.setOmitComments(true);

There are a few constants but I think you can guess them yourself;) and otherwise you know how to ask me for them:)
The RoosterItem class will hold all variables of an hour, and the RoosterItems will hold more than one RoosterItem
Good Luck!

So far i think JSoup is one of the best way to extract or manipulate the HTML.....
See this link :
http://jsoup.org/
But somehow.... this did't worked in my case, so i converted the entire HTML code into String, then parsed it.....

This program gives java heap out of space and when excel sheet containing 16 columns is uploaded it gives ArrayIndexOutOfBoundException.I had increased memory of eclipse upto -Xmx1600m but that also didnt work.

You get the ArrayIndexOutOfBoundException on the values array because you use the row.getPhysicalNumberOfCells() to determine its size. But row.getPhysicalNumberOfCells() will only count the cells that are actually filled in the file.
For example if you create an Excel sheet and only fill columns A, C and F and don't touch the other cells at all row.getPhysicalNumberOfCells() will return 3.
But you are iterating over all the cells by getting row.getFirstCellNum() and row.getLastCellNum(). So values[iCurrent] will sure be out of bounds once you reach cell F.
Regarding the OutOfMemory issue:
XSSF uses a LOT of memory. Try pushing your VM to as much memory as is possible for your machine. Or if you are just reading the files then try to go with the eventmodel API instead of the usermodel (think SAX vs. DOM).
