Hi
I am facing one problem. there is some data should be displayed in Jtable cell.
The thing is that the whole data shall be visible in the cell.. for this I am writing one renderer.. but I could not find the desire solution.. please check it out
class Item_Details extends JFrame {
    ApsJTable itemTable = null;
     ApsJTable imageTable = null;

          try{
                    data1 = getRowData1();
             }catch(Exception e){}

     }what wrong with this code..

In summary, you have one or more columns for which the data must be wholly visible - correct? If you need all the columns to show the whole of their data, you are goinf to have to expand the table, otherwise you can expand a column with something like
myTable.getColumnModel().getColumn(whichever).setPreferredWidth(whatever);
