将MapType col转换为Json：DataFrame

Question

我有一个数据框，内容如下：

if (value.length >= 3)

我想在Json中将其转换，例如

plugins: [
  new HtmlWebpackPlugin({
    title: 'Custom template',
    // Load a custom template (lodash by default)
    template: 'index.html'
  })
]

我尝试了<table [dataSource]="(searchResults$ | async)?.accounts" mat-table matSort multiTemplateDataRows> <ng-container matColumnDef="Code"> <th *matHeaderCellDef mat-header-cell mat-sort-header> Account Code</th> <td *matCellDef="let account" mat-cell> {{account.code}} </td> </ng-container> </table> ，但是在运行AnalysisException时却得到了AnalysisException。
