Auto Resize JTable Columns
|
|
This class auto resizes columns of a JTable, maximizing any non-used width columns and transferring those extra widths to other columns. This way, a column with a JCheckBox will have a width almost equal to that of a JCheckBox‘s width. The class TableColumnResizer contains one static method and you can pass the JTable object as the parameter. The code does the rest.
To use the method, do this:
1 | TableColumnResizer.adjustColumnPreferredWidths(myJTableObject); |
Here is the code of the TableColumnResizer class.
1 2 3 4 5 6 7 8 9 10 | public class TableColumnResizer { public static void adjustColumnPreferredWidths(JTable table) { if (table == null || table.getColumnCount() == 0) return; // strategy - get max width for cells in column and // make that the preferred width TableColumnModel columnModel = table.getColumnModel(); for (int col=0; col |
