JTable column sizing

[Daniel Luis dos Santos]

Hello,

I have a JTable with some columns. I am setting the widths of some
columns to some preferred size. One column has no header text, and the
cells have a check box. I want the cells of that column to have the
least amount of extra width around the check boxes. I set the preferred
size on the table column to be 1 or 0 and the there is always space
around the check boxes. Is it possible to remove that extra space. I
have the same problem on some other columns.

Those columns on which I am setting the width, I am also setting them
not to be resizable. But when I resize the window (and thus the table),
the non-resizable columns also resize proportionally. Can I tell them
to be fixed size no matter what width the table has ?

Thanks.

You could override the check box's paintBorder() method or change the
borderPainted property.
