为JTable添加单元格工具提示

覆盖JTable的getToolTipText(MouseEvent e)方法

@Overridepublic String getToolTipText(MouseEvent e) {int col = columnAtPoint(e.getPoint());if (col != 0) {return null;}int row = rowAtPoint(e.getPoint());String toolTip = null;if (row > -1 && col > -1) {Object value = getValueAt(row, col);if (value != null && !value.toString().isEmpty())toolTip = value.toString();}return toolTip;}
