Usage

From source file:Main.java

public void mouseClicked(MouseEvent evt) {
    JTable table = ((JTableHeader) evt.getSource()).getTable();
    TableColumnModel colModel = table.getColumnModel();

    int index = colModel.getColumnIndexAtX(evt.getX());
    if (index == -1) {
        return;/* ww w . j ava2s .  c om*/
    }
    Rectangle headerRect = table.getTableHeader().getHeaderRect(index);
    if (index == 0) {
        headerRect.width -= 10;
    } else {
        headerRect.grow(-10, 0);
    }
    if (!headerRect.contains(evt.getX(), evt.getY())) {
        int vLeftColIndex = index;
        if (evt.getX() < headerRect.x) {
            vLeftColIndex--;
