Removing the Cell Gap between Jtable Columns

Question

I am populating the jTable from DB but puts gap for each cell up to beginning of the next column shown in picture below , how to fix that ? I will be happy you can comment on this thanks.

Answer 1

In your code, you must have a reference to your JTable

You can use something like this.

yourTable.getColumnModel().getColumn(0).setPreferredWidth(10);
yourTable.getColumnModel().getColumn(1).setPreferredWidth(20);
