组合表头

通过 Grid::combine 方法可以很方便的把任意两个以上的字段组合成一级表头

示例

protected function grid()
{
    return Grid::make(new Report(), function (Grid $grid) {
        // 第一个参数为一级表头字段名称，第二个字段为二级表头字段名称，二级表头字段最少设置两个
        $grid->combine('avgCost', ['avgMonthCost', 'avgQuarterCost', 'avgYearCost']);
        // 启用RWD-Table-Patterns插件
        $grid->combine('avgVist', ['avgMonthVist', 'avgQuarterVist', 'avgYearVist'])->responsive();
        // 启用RWD-Table-Patterns插件并设置样式
        $grid->combine('top', ['topCost', 'topVist', 'topIncr'])->responsive()->style('color:#1867c0');
        $grid->content->limit(50)->responsive();
        $grid->cost->sortable()->responsive();
        $grid->avgMonthCost->responsive();
        $grid->avgQuarterCost->responsive()->setHeaderAttributes(['style' => 'color:#5b69bc']);
        $grid->avgYearCost->responsive();
        $grid->avgMonthVist->responsive();
        $grid->avgQuarterVist->responsive();
        $grid->avgYearVist->responsive();
        $grid->incrs->hide();
        $grid->avgVists->hide();
        $grid->topCost->responsive();
        $grid->topVist->responsive();
        $grid->topIncr->responsive();
        $grid->date->sortable()->responsive();
    });
}
