e909. Inserting a Row in a JTable ComponentTo insert a row of data to aJTable component, you need to insert it
to its table model. A simple implementation of a table model that
supports the insertion of row data is DefaultTableModel .
When inserting a row using When inserting a row with fewer values than columns, the left-most fields in the new row are populated with the supplied values (left-to-right) and the fields without values are set to null. When inserting a row with more values than columns, the extra values are ignored. DefaultTableModel model = new DefaultTableModel(); JTable table = new JTable(model); // Create a couple of columns model.addColumn("Col1"); model.addColumn("Col2"); // Create the first row model.insertRow(0, new Object[]{"r1"}); // Insert a row so that it becomes the first row model.insertRow(0, new Object[]{"r2"}); // Insert a row at position p int p = 2; model.insertRow(p, new Object[]{"r3"}); // Insert a row before the second row int r = 1; model.insertRow(r, new Object[]{"r4"}); // the new row is now the second row // Insert a row after the second row r = 1; model.insertRow(r+1, new Object[]{"r5"}); // the new row is now the third row // Append a row model.insertRow(model.getRowCount(), new Object[]{"r5"});
