Select all data when start editing JTable Cell

Question

I'm trying to make a table that works like Excel. Meaning, when a user starts to insert data into the cells the content into them is selected and changed by the new data inserted.

You can create a custom TableCellEditor for your table. This class will have an instance variable of a TextField, lets call it textField. Then the getTableCellEditorComponent method could look like this:

public Component getTableCellEditorComponent(JTable table, Object value, 
                             boolean isSelected, int row, int column ) {
    textField.setText(value.toString());
    textField.selectAll();
    return textField;
}
