如何在nattable中配置字体颜色

@Override
public void paintCell(ILayerCell cell, GC gc, Rectangle bounds, IConfigRegistry configRegistry) {
    super.paintCell(cell, gc, bounds, configRegistry);

    // 获取单元格的值
    Object cellValue = cell.getDataValue();

    // 根据值设置字体颜色
    if (cellValue != null && cellValue.equals("某个特定值")) {
        gc.setForeground(Display.getCurrent().getSystemColor(SWT.COLOR_RED));
    } else {
        gc.setForeground(Display.getCurrent().getSystemColor(SWT.COLOR_BLACK));
    }

    // 绘制文本
    TextUtilities.drawAlignedString(
        gc,
        cell.getText(),
        bounds.x + padding,
        bounds.y + padding,
        bounds.width - (2 * padding),
        bounds.height - (2 * padding),
        cell.getHorizontalAlign(),
        cell.getVerticalAlign(),
        false
    );
}

// 获取配置注册表
IConfigRegistry configRegistry = natTable.getConfigRegistry();

// 创建自定义渲染器
ICellPainter cellPainter = new CustomCellPainter();

// 将渲染器注册到列上
configRegistry.registerConfigAttribute(
    CellConfigAttributes.CELL_PAINTER,
    cellPainter,
    DisplayMode.NORMAL,
    "columnLabel"
);
