How to remeve a row from a JTable.
This example illustrates how to remove a row from an existing JTable called table.
The row to be deleted will be the row that has been selected by clicking the mouse on it.
//CREATE MODEL INSTANCE FROM EXISTING TABLE
DefaultTableModel model = new DefaultTableModel();
model = (DefaultTableModel) table.getModel();//DELETE THE SELECTED ROW
model.removeRow(table.getSelectedRow());
//INSERT A NEW EMPTY ROW
model.addRow(new Object[]{“”,””,””});
I used this with a confimation dialog, asking the user to confirm this is the correct row to be deleted;
int n = JOptionPane.showConfirmDialog(
null,
“Are you sure you want delete – ” + table.getValueAt(table.getSelectedRow(), 2) + “?”,
“”,
JOptionPane.YES_NO_CANCEL_OPTION);
//the user has clicked the cross
if(n == -1)
{
return;
}
//the user has clicked cancel
if(n == 2)
{
return;
}
//yes
if(n == 0){
//CREATE MODEL INSTANCE FROM EXISTING TABLE
DefaultTableModel model = new DefaultTableModel();
model = (DefaultTableModel) table.getModel();
//DELETE THE SELECTED ROW
model.removeRow(table.getSelectedRow());
//INSERT A NEW EMPTY ROW
model.addRow(new Object[]{“”,””,””});
}
//no
if(n == 1){
return;
}
