e908. Appending a Row to a JTable ComponentTo add a row of data to aJTable component, you need to add it to
its table model. A simple implementation of a table model that
supports appending row data is DefaultTableModel . By
default, a table uses a DefaultTableModel .
DefaultTableModel model = new DefaultTableModel(); JTable table = new JTable(model); // Create a couple of columns model.addColumn("Col1"); model.addColumn("Col2"); // Append a row model.addRow(new Object[]{"v1", "v2"}); // there are now 2 rows with 2 columns // Append 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 fields // without values are set to null. model.addRow(new Object[]{"v1"}); // there are now 3 rows with 2 columns // Append a row with more values than columns. // The extra values are ignored. model.addRow(new Object[]{"v1", "v2", "v3"}); // there are now 4 rows with 2 columns
