ag-grid 设置单元格以及行的颜色

大家好，又见面了，我是你们的朋友全栈君。

在使用ag-grid的时候有通过单元格的值设置不同行颜色，然后百度了网上的方法，汇总了一下，具体效果图如下：

话不多说，直接上代码。

    <div id="myGrid" style="width: 100%;height: 500px;" class="ag-theme-alpine"></div>

    <script>

        var columnDefs = [
            {
                headerName: '基本信息',
                children: [
                    {
                        headerName: '班级',
                        field: 'class',
                        cellRenderer: changeCellColor


                    }, {
                        headerName: '姓名',
                        field: 'name',
