Removing a Row from a JTable Component
To remove a row of data from a JTable component, you need to remove it
from its table model. A simple implementation of a table model that
supports the removal of row data is DefaultTableModel.
When removing a row using DefaultTableModel.removeRow(), the
index of the row must be specified. Row indices start from 0. For
example, if there are 2 rows in a table, the index of the first row
is 0 and the index of the second row is 1.
Removing a row at index 0 removes the first row.
DefaultTableModel model = new DefaultTableModel();
JTable table = new JTable(model);
// Create some data
model.addColumn("Col1");
model.addRow(new Object[]{"r1"});
model.addRow(new Object[]{"r2"});
model.addRow(new Object[]{"r3"});
// Remove the first row
model.removeRow(0);
// Remove the last row
model.removeRow(model.getRowCount()-1);
