如何从表中删除所选内容?

您必须添加 [(selection)]="selectedRow" 在 p-table 要将所选行绑定到已定义的变量,请执行以下操作:

<p-table [value]="tableData" selectionMode="single" metaKeySelection = "true" [(selection)]="selectedRow">
<ng-template pTemplate="header">
    <tr>
        <th>Company</th>
        <th>First Name</th>
        <th>Email</th>
    </tr>
</ng-template>
<ng-template pTemplate="body" let-rowData let-rowIndex="rowIndex">
    <tr [pSelectableRow]="rowData">
        <td>{{rowData.first_name}}</td>
        <td>{{rowData.last_name}}</td>
        <td>{{rowData.email}}</td>
    </tr>
</ng-template>
</p-table>

<button (click)= "removeSelection()">Remove Selection</button>

并添加 this.selectedRow = null; 在 removeSelection() 方法:

removeSelection() {
    this.selectedRow = null;
}
