初始化表格组件无法与ngFor一起使用 [英] Primeng the table component isn't working with ngFor

问题描述

我试图循环一个数组，该数组中的每个对象都是html上的表格.它显示如下:

i am trying to loop an array each object in this array is a table on html. and it display like this :

<p-table [value]="section" *ngFor="let section of sections">
  <ng-template pTemplate="header">
          <tr>
              <th>Quantity</th>
              <th>Length</th>
              <th>m^2</th>
              <th></th>
          </tr>
          <tr>
              <th colspan="4">
                  <div (click)="showDialog()" class="text-left">+ A - Flat Panel RAW MDF Red Gloss
                      - $95 / sqm
                  </div>
              </th>
              <th colspan="8">
                  <div class="md-inputfield">
                      <input type="text" class="form-control" pInputText>
                  </div>
              </th>
          </tr>
      </ng-template>
      <ng-template pTemplate="body" let-rowData *ngFor="let piece of rowData.Pieces">
          <tr>
              <td>
                  <p-spinner [(ngModel)]="rowData.Quantity"></p-spinner>
              </td>
              <td pEditableColumn>
                  <p-cellEditor>
                      <ng-template pTemplate="input">
                          <input type="text" [(ngModel)]="rowData.Length">
                      </ng-template>
                      <ng-template pTemplate="output">
                          {{rowData.Length}}
                      </ng-template>
                  </p-cellEditor>
              </td>
              <td>
                  {{CalculateTotalArea(rowData)}}
              </td>
              <td>
                  <button pButton type="button" icon="fa-close"></button>
              </td>
          </tr>
      </ng-template>
</p-table>

但这给我一个错误 this.value.sort不是一个函数，这里是数组

but this give me an error this.value.sort is not a function and here is array

this.pieces = [{数量:2，长度:3，宽度:3，厚度:4}]

this.sections = [{件:this.pieces，文本:"abc"}]

我正在尝试将代码推送到Plunker中，但是我不知道如何将primeng版本升级到"primeng":"^ 5.2.0-rc.1"，然后Plunker是现在不工作任何人都可以帮助我更新primeng库并建议我如何解决此错误.这是Plunker的链接: Plunker

i am trying to push code into Plunker but i don't know how to upgrade version of primeng to "primeng": "^5.2.0-rc.1", then the Plunker is't working right now anyone help me update the primeng library and suggest me how to resolve this bug . here is the link Plunker : Plunker

推荐答案

这是因为，p表希望通过 value 的数组，但是您正在传递 {个数:this.pieces，文本:"abc"} 会导致错误.您必须删除 * ngFor ="section of section" 并像这样传递您的数组< p-table [value] ="sections"> ，或者如果您确实希望在页面中包含一堆表，则 sections 数组应类似于以下(多维):

It is because, p-table expects an array through value however you are passing { Pieces: this.pieces, text: "abc" } which causes the error. Either you have to remove *ngFor="let section of sections" and pass your array like this <p-table [value]="sections"> or if you really want to have bunch of tables in your page, your sections array should be like following (multidimensional):

// for the sake of simplicity, I named your objects as 'item'
this.sections = [
    [item1, item2, item3],
    [item10, item11, item12],
    [item15, item50, item32]
]
