JTable中如何给某个cell设置背景色,注意不是某列?

[javafounder]

根据CellRenderer中传进来的参数，可以确定是哪个cell，然后设置其颜色

给JTable加绘制器.以下是我写的一个绘制器.注意那个else,不可少.

class ColorRenderer extends DefaultTableCellRenderer
{
int _row;
public Component getTableCellRendererComponent( JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column )
{
isSelected = false;
super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);

if((String)table.getValueAt(row,0) == "●運用情報"||(String)table.getValueAt(row,0) == "●設定情報")
{
setBackground(Color.YELLOW);
}
else
{
setBackground(table.getBackground());
}
return this;
}
}


加绘制器的代码:
TableColumnModel cmodelItemModel =_jTableInfo.getColumnModel();
TableColumn columnItem = cmodelItemModel.getColumn(0);
columnItem.setCellRenderer( new ColorRenderer() );
