Enabling Row, Column, or Cell Selections in a JTable Component
With row selections enabled, clicking on any cell selects the entire
row containing that cell. This also applies to columns. With cell
selections enabled, rectangular blocks of cells can be selected.
JTable table = new JTable();
// Enable row selection (default)
table.setColumnSelectionAllowed(false);
table.setRowSelectionAllowed(true);
// Enable column selection
table.setColumnSelectionAllowed(true);
table.setRowSelectionAllowed(false);
// Enable cell selection
table.setColumnSelectionAllowed(true);
table.setRowSelectionAllowed(true);
