e921. Inserting a Column in a JTable ComponentThere is no insertColumn method likeDefaultTableModel.insertRow() for inserting rows. In order to
insert a column at a particular position, you must append the column
using DefaultTable.addColumn() and then move the new column into
the desired position.
See e920 Appending a Column to a JTable Component and
e923 Moving a Column in a JTable Component for more information.
int rows = 10; int cols = 5; JTable table = new JTable(rows, cols); // Disable autoCreateColumnsFromModel table.setAutoCreateColumnsFromModel(false); // Add data // Insert a new column at position 2 (becomes 3rd column) insertColumn(table, "New Column", null, 2); // Insert a new column at the end insertColumn(table, "New Column", null, table.getColumnCount()); // Creates a new column at position vColIndex public void insertColumn(JTable table, Object headerLabel, Object[] values, int vColIndex) { // This method is defined in // e920 Appending a Column to a JTable Component betterAddColumn(table, headerLabel, values); table.moveColumn(table.getColumnCount()-1, vColIndex); }
