在我的应用程序中我使用fexbox概念来显示公司名称和材料的headcompany。我在这里使用了ngx-datatable。我将columnmode设置为flex。现在我将每列的flexgrow设置为1.我想为这两列的flex-grow写一个if-else条件。例如，如果按下selectedCompany，则第二列增长为2，否则为1。
<ngx-datatable *ngIf="companies && companies.length" class="material" [scrollbarH]="true" [rows]="companies" [externalPaging]="true" [externalSorting]="true" [count]="companyPage.totalElements" [offset]="companyPage.number" [limit]="companyPage.size"
[columnMode]="'flex'" [footerHeight]="'auto'" [headerHeight]="'auto'" [rowHeight]="'auto'" (page)='onCompanyPageEvent($event)' (sort)='onCompanySortEvent($event)' (activate)="onActivateCompany($event)">
<ngx-datatable-column [prop]="'name'" [flexGrow]="1" >
<ng-template ngx-datatable-header-template >
<span class="ellipsis" title="{{value}}">
{{'A921Name' | translate}}
</span>
</ng-template>
</ngx-datatable-column>
//我试着写if-else here
<ngx-datatable-column [prop]="'parentName'" *ngIf="selectedCompany" [flexGrow]="2" [sortable]="false" >
<ng-template ngx-datatable-header-template>
<span class="ellipsis" title="{{value}}">
{{'A922ParentCompany' | translate}}
</span>
</ng-template>
</ngx-datatable-column>
</ngx-datatable>

当您使用方括号包装属性时，可以将其设置为动态。这意味着它将在各自的typescript类中查找属性。因此，对于像此处[footerHeight]="'auto'"那样的静态值，在将footerHeight设置为字符串'auto'时，不需要使用方括号括起footerHeight="auto"。你可以export class RelatedPage {
footerHeightValue: string;
constructor(){
this.footerHeightValue = 'auto';
}
}
。但是，如果您的typescript类中有一个属性，其中包含footerHeight的字符串值，例如：
footerHeight然后您可以执行动态绑定并将[footerHeight]="footerHeightValue"设置为相应的属性，如[attribute];
因此，当您想要在某个条件语句中更改属性的值时，您希望使属性动态化为flexGrow。在您的情况下，如果您的<span (click)="titleClicked()">{{companyName}}</span>
属性必须根据标题是否被点击而更改，您可以将tap事件绑定到布尔值。
export class RelatedPage {
titleSelected: boolean;
titleClicked() {
this.titleSelected = true;
}
}
并在你的打字稿类中，
titleSelected现在，您可以将flexBox属性与flexBox]="titleSelected ? 2 : 1"属性绑定，如下所示
[if (titleSelected === true) {
flexBox = 2;
} else {
flexBox = 1;
}
