Auto resizing the JTable column widths

Question

I need my JTable to automatically re-size its column widths to fit the content. I found the TableColumnAdjuster class very useful. But there\'s a small problem. Say i have 5

Answer 1

There is no option to automatically resize one column larger than the other.

Maybe you can to something like:

tca = new TableColumnAdjuster( table, 0 );
tca.adjustColumns();
TableColumnModel tcm = table.getColumnModel();  
TableColumn tc = tcm.getColumn(1);
tc.setWidth(tc.getWidth() + 25);

This would allow you to add extra space to column 1. This extra space would only be added the first time the table is displayed.

Another option is to use:

table.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);

This would allocate extra space proportionally to each column.
