是否必须突出显示单元格的决定必须在TableCellRenderer中进行。它不能在JTable中进行。因此，（没有）没有理由要重写JTable中的方法。相反，您可以将列的CellRenderer设置为TableCellRenderer的自己实现。
在此示例中，列2和3接收“
ColoringCellRenderer”。如果此单元格中的值不为null且与列1中的值相同，则此ColoringCellRenderer将突出显示该单元格。

该类使用两个类“ DelegatingTableCellRenderer”和“
DelegatingTableCellEditor”。这些类各自接收各自的委托，并且仅设置委托所传递的单元格组件的背景色。
这样，着色表单元格（用于渲染器或编辑器）的功能就与实际渲染器分离了。因此，可以为默认的CellRenderer的背景着色（例如
Boolean显示JCheckBox的值）。
