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
