I have 3 columns for a table, with fixed scroll pane dimensions.
3rd column has data exceeding the column length.
To see the data in column 3 i need to resize the whole window it is embedded in.
Instead i want to have 3 columns stretched to its max data length.
And if this exceeds the dimensions of the scroll pane i would like to have a horizontal scroll bar.
==========
So the 1st thing to achieve is how can i specify "stretch the column to its max data length".
Example Code Without the feature

import javax.swing.*;
import javax.swing.plaf.basic.BasicBorders.MarginBorder;
import javax.swing.plaf.metal.MetalBorders.TableHeaderBorder;
