Im created a JTable,but im not able to read the lengthy text when it is bigger than the cell width.So, i want the text to be be align in the next line of that cell same as in excel sheet.
Can anyone help me in this.
Thank you

Aligning the Text in Centre for MultiLine Cells in JTable
Hi;
Does anyone know how I could make a java table that has multiline text cells AND this multiline text is aligned to center? I tried to extend JTextArea and to implement TableRenderer - multiline was OK but it did not do anything on setHorizontalAlign. If I extend DefaultTableRender than I can align the text to center but I got no multiline...
Any ideas?
Kindly to provide me a solution for this its urgent.Hi;
Thanks for the reply,on using Text Area as renderer i.e using Multi-Line cells in JTable, i achieved the objective of displaying the text on multiple lines in the cell."In my Table there are 5 columns and i'm setting renderer on 3rd and 5th column,If the text is too large in column 5 it automatically gets wrapped off for all the cells in column 5.For column 3 my text is not so large as compared to column 5 and due to which the Text in the column 3 starts from the top for all the cells i.e (the first row in column 3 is parallel to first row in column 5 ),Now the problem is i can't display the text in the center of all cells for Column 3 .
Thanks in advance -

Sometime i get more than 1 value for some column e.g Surgery Name and Surgeon Name, so
i want to display more than 1 value in the same cell. like bellow i have mentiond for

I know that can be taken care with Renderer, i tried but couldn't go through. I have written TableRenderer

hi all
i found in this forum a class that implements TableCellRenderer and that should allow my table to have multiline cells. i need it because if the content of my cell (retrieved via jdbc from a db) exceeds the cell width is truncated and a "..." appears.
so i searched, i founded and i tried some example but with no results. i don't know where is the mistake, also because the code should work.
i'll post the class code and my table's code and i hope someone could help me!!!

thanx a lotthanx to all my friends, but i still have my problem..
viravan, i'm using the same MultiLineCellRenderer class as the example, the only thing different is my class from where i set the MultiLineCellRenderer the default Renderer for my table
this is the code: (i post it because i didn't found any significant difference between the example class and the one of mine...) i suspect there is some problem in the table setting... but i don't know where...

Change the background color of a cell in JTable
Hi all,
How can I change the background color of individual cell in JTable. I need to construct my own TableCellRenderer or not? I'm now using the DefaultTableCellRenderer now.
ThxYou could create your own renderer or you could try something like:
table = new JTable(model)
public TableCellRenderer getCellRenderer(int row, int column)
DefaultTableCellRenderer tcr =
(DefaultTableCellRenderer)super.getCellRenderer(row, column);
if (row == 1 && column == 1)
tcr.setBackground(Color.green);
else
tcr.setBackground(Color.red);
return tcr;

Setting Focus to a particular cell in JTable
Hi, can i know how to set the focus to a particular cell in JTable.
Say I have a table with 2 rows and 10 columns. The focus now is at position (1, 9) which is the last cell in the table. But I want to set the focus to (1, 3). How can i achieve this ? Pls help. ThanksOK. It's partially working. The right methods to use are setRowSelectionInterval and setColumnSelectionInterval. Jeanette was right. Mine didn't work because of a thread issue. I put the those two methods in a block such as:
SwingUtilities.invokeLater(new Runnable(){
public void run()
table.setRowSelectionInterval(tblLineItem.getRowCount()-1,
table.getRowCount()-1);
table.setColumnSelectionInterval(0,0);
Then it worked.
But after I finished editing the first cell of the newly created row and press ENTER, the selection went back to the cell that's next to the originally editing cell on the first(old) row, instead of staying at the current row and going to the second cell.
Can anybody shed a light on what I'm missing? -
How to disable a particular cell in JTable ?
I having a problem on how to set disable a particular cell in JTable. At the first place to load the JTable, I want to set some of the cell to disabled, it only will run at the first time, is there anyway to do it ?
This is the function that disable/enable cells in JTables.
Are you looking for this?
public boolean isCellEditable(int row, int col)
if(((new Integer((String)(getValueAt(row,0)).toString()).intValue()>9))&&(col==1))
return true;
if(row!=4&&col!=5)
return true;
return false;
this metod belong to the TableModel function
and what I gave you is only an example of what you can do with it.
if it return false it disable and if true it enable the cell...but I think this you allready know!

Problem with select all cells in JTable
Hi guys! I get some problem about selecting all cells in JTable. I tried to used two methods:
1> table.selectAll()2> changeSelection(firstcell, lastcell,false,true)
firstcell:[0,0], lastcell[rowcount-1,colcount-1]
Result: only the first row selected when i use both methods.
Note: i set up the selection model as following:
this.dataSheet.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
this.dataSheet.setCellSelectionEnabled(true);
this.dataSheet.setRowSelectionAllowed(true);
this.dataSheet.setColumnSelectionAllowed(true);Thanks !What selection properity should be changed in order to enable selectAll() method work properly? Is there Any constraints? Here is the TableModel I am using. And i set up selection mode use the following code:
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
table.setCellSelectionEnabled(true);
table.setRowSelectionAllowed(true);
table.setColumnSelectionAllowed(true);
