Setting the Width of a Column in a JTable Component

By default, the column widths of all columns are equal. In order for column width adjustments to be made, autoResizeMode must be disabled.
int rows = 3; int cols = 3; JTable table = new JTable(rows, cols); // Disable auto resizing table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); // Set the first visible column to 100 pixels wide int vColIndex = 0; TableColumn col = table.getColumnModel().getColumn(vColIndex); int width = 100; col.setPreferredWidth(width);

FWIW, you don't have to turn autoResizeMode off, comment out that last line and if any columns are left at an unspecified length, they auto resize to fill the table's specified width.
