Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    JTable table = new JTable();

    if (table.getCellSelectionEnabled()) {
        // In the other modes, the set of selected cells can be retrieved using
        table.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION);
        table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);

        // Get the min and max ranges of selected cells
        int rowIndexStart = table.getSelectedRow();
        int rowIndexEnd = table.getSelectionModel().getMaxSelectionIndex();
        int colIndexStart = table.getSelectedColumn();
        int colIndexEnd = table.getColumnModel().getSelectionModel().getMaxSelectionIndex();

        // Check each cell in the range
        for (int r = rowIndexStart; r <= rowIndexEnd; r++) {
            for (int c = colIndexStart; c <= colIndexEnd; c++) {
