Hiding JTable Columns

[Ajit Kumar]

Hi,
How do i hide a specific column in a JTable object.?
Setting setPreferredSize to 0 is not working.
Any suggestions?
Thanks

Hi Ajit,
to set the columnwidth to zero u need to set all three
setMaximumWidth(0);
setPreferredWidth(0);
setMinimumWidth(0);
setPreferredWidth(0) does not work alone.
regards

Hi,
This is not working for me. I still get a phantom column, about 1 character wide.
I have tried and tried to make it go away, but it persists.

Any ideas?

I finally found the answer!
column = table.getColumnModel().getColumn(col_numb_to_be_hidden);
table.removeColumn(column);

Try this !!
It worked for me !!
Good luck .. Sandhya
TableColumn column1 = null;
column1 = JTable1.getColumnModel().getColumn(no. of the col you want to hide);
column1.setMaxWidth(0);
column1.setMinWidth(0);
column1.setWidth(0);
column1.setPreferredWidth(0);

How do you hide more than one column and make it/them return when you want???

Hi.
I use following solution for alternate visibility of two column:

public class ...
{
 
   private JTable      table;
   private TableColumn column_name,   //column of only file names
                       column_path;   //column of paths
   ...
 
   public void an_method_of_init()
   {
      table = ...
 
      for(int a=0, b=table.getColumnCount(); a<b; a++)
      {  TableColumn c = table.getColumnModel().getColumn(a);
         switch(a) {
         case 0: c0 = c; break;
         case 1: c1 = c; break;
         }
      }
 
   }
 
   public void swap(boolean f)
   {  TableColumn c0, c1;
      if(f)
      {  c0 = column_name;                          //column to hiding
         c1 = column_path;                          //column to adding
      }
      else
      {  c0 = column_path;                          //idem bat inverse
         c1 = column_name;
      }
      int i = table.getColumnIndex(c0);
      table.removeColumn(c0);                       //hide column c0
      table.addColumn(c1);                          //add column c1
      table.moveColumn(table.getColumnCount()-1,i); //adjust position of c1
      if(c1.getWidth()!=c0.getWidth()) c1.setWidth(c0.getWidth());
   }                                                //adjust width of c1
 
}

Thanks for suggest.
