刷新网格

Question

我正在使用ag-grid显示数据。但是，并不是网格中的所有数据都来自我传递给gridAPI的rowData。 其中一列是根据行数据和其他数据集计算得出的。当单击一个对话框时，网格还具有编辑按钮，用户可以在其中更改其中一个值并保存到服务器。保存操作完成后，对话框关闭，并将控制权传递给Grid，但是Grid单元格不刷新。我知道为什么网格不刷新。因为我传递的rowData没有直接更新，但是另一组数据已更改，因此我根据该数据计算了一个列值。我的代码如下。如果看到方法getDefaultMArketName用作第二列的valueGetter。这导致网格无法更新。有指针吗？

    type Props = {
    companiesWithMarket: any;
    defaultMarkets:any;
    editMyPreferences?:(companyWithMarket:any)=>void;
    }

    export class MyGrid extends React.PureComponent<Props, State> {

    static contextTypes = {

    getColumns = memoizeOne( (editMyPreferences): Array<ColDef> =>{
