Question

我正在使用带有可编辑选项true的PrimeNg数据表。我收到了以下错误：

错误：

ERROR in Error at D:/Project/ui/src/app/pages/admin/components/dashboard/dashboard.component.html(38,31):  ("lumn.isSortab
le" [style]="column.columnStyle?column.columnStyle:{}">
                    <template [ERROR ->]let-col let-row="rowData" pTemplate="editor">
                      <textarea *ngIf="column.isEditab")
Error at D:/Project/ui/src/app/pages/admin/components/dashboard/dashboard.component.html(38,39):  ("ortable" [style]="colu

                      <textarea *ngIf="column.isEditableAsText")

DataTable HTML：

<p-dataTable *ngIf="showTable()" [value]="tableConfig.data" [dataKey]="'id'" [rowStyleClass]="highLightUnsavedRow" [lazy]="true" [rows]="10" [paginator]="true" [responsive]="true" [totalRecords]="getTotalRecords()" (onLazyLoad)="onRowEvent($event)" [(selection)]="selectedRows"
                    (onRowSelect)="onRowSelect($event)" (onRowUnselect)="onRowUnselect($event)" [editable]="true" (onHeaderCheckboxToggle)="onHeaderCheckboxToggle($event)" (selectionChange)="onSelectionChange($event)">
                    <p-header>Header</p-header>
                    <p-column *ngIf="tableConfig.isMultiSelect" [style]="tableConfig.multiSelectColStyle?tableConfig.multiSelectColStyle:{'width':'38px'}" selectionMode="multiple"></p-column>
                    <p-column *ngFor="let column of tableConfig.columns" field="{{column.fieldName}}" header="{{column.columnTitle?column.columnTitle:column.fieldName}}" [filter]="column.isFilterable" [editable]="column.isEditable" [sortable]="column.isSortable" [style]="column.columnStyle?column.columnStyle:{}">
                        <template let-col let-row="rowData" pTemplate="editor">
                          <textarea *ngIf="column.isEditableAsText" class="edit-field" [(ngModel)]="row[col.field]" (change)="onTableEditTextBoxChange(row,col.field,row[col.field])"></textarea>
                          <p-dropdown *ngIf="column.isEditableAsDropDown" class="edit-field" autoWidth="false" [style]="column.editFieldStyle?column.editFieldStyle:{}" [(ngModel)]="row[col.field]" [options]="column.editDropDownOptions"></p-dropdown>
                        </template>
                    </p-column>
                </p-dataTable>

问题在于以下标记的 let-col 和 let-row =“rowData”属性：

<template let-col let-row="rowData" pTemplate="editor">

如果我删除这两个属性，那么构建问题就会消失，但表格会呈现0行。

必须在Angular 5中使用

ng-template

<ng-template let-col let-row="rowData" pTemplate="editor">

现在出现错误，因为它已在角度4.x

中弃用

注意：

您仍然可以通过将编译器选项中的<template>标记设置为enableLegacyTemplate来使用true，该标记可以配置为

在 main.ts

中

const compilerOptions: CompilerOptions = {
  enableLegacyTemplate: true
};

将模块中的值用作

platformBrowserDynamic().bootstrapModule(AppModule,compilerOptions)

PrimeNg DataTable无法使用Angular 5
