復合If語句未評估為真Angular

Question

我有以下代碼塊：

<tbody>
    <tr *ngFor="let row of model">
        <ng-container *ngFor="let columnDataName of columnDataNames">
            <td *ngIf="modelConfig[columnDataName] && modelConfig[columnDataName].isVisible">
                <ng-template *ngIf="showRowTextBox && columnDataName === conditionalInputName || columnDataName === conditionCheckBoxName; else otherColumns">
                    <ng-container *ngIf="columnDataName === conditionalInputName">
                        <input type="text" placeholder="Enter text here" [hidden]="!chkEnabled?.checked" (focusout)="onTextBoxFocusOut(row[primaryKeyColumnName], $event)" />
                    </ng-container>
                    <ng-container *ngIf="columnDataName === conditionCheckBoxName">
                        <input type="checkbox" [checked]="chkAll?.checked" #chkEnabled ngModel />
                    </ng-container>
                </ng-template>
                <ng-template #otherColumns>
                    <ng-container *ngIf="modelConfig[columnDataName].isDate;">
                        {{ row[columnDataName] | date:'d MMM yyyy' }}
                    </ng-container>
                    <ng-container *ngIf="modelConfig[columnDataName].isBoolean;">
                        <tfg-toggle onText="Yes" offText="No" [disabled]="true" [value]="row[columnDataName]"></tfg-toggle>
                    </ng-container>
                    <ng-container *ngIf="!modelConfig[columnDataName].isBoolean && !modelConfig[columnDataName].isDate">
                        {{ row[columnDataName] }}
                    </ng-container>
                </ng-template>
            </td>
        </ng-container>
        <td *ngFor="let buttonColumnName of buttonColumnNames">
            <button (click)="executeButtonFunction(row[primaryKeyColumnName], buttonColumnName)" class="btn" [ngClass]="buttonColumnName === 'Delete' ? 'btn-danger' : 'btn-primary'">{{buttonColumnName}}</button>
        </td>
        <!-- <ng-container *ngIf="showRowTextBox">
            <td>
              <input type="text" placeholder="Enter text here" [hidden]="!chkEnabled.checked" (focusout)="onTextBoxFocusOut(row[primaryKeyColumnName], $event)"/>
            </td>
            <td>
              <input type="checkbox" [checked]="chkAll?.checked" #chkEnabled ngModel/>
            </td>
          </ng-container> -->
    </tr>
</tbody>

該頁面未按預期呈現，因為下面的if語句的求值結果為true。

<ng-template *ngIf="showRowTextBox && columnDataName === conditionalInputName || columnDataName === conditionCheckBoxName; else otherColumns">

ShowRowTextBox設置為true，並且在迭代的某個時刻， columnDataName將等於conditionalInputName或condtionCheckBoxName 。

我的邏輯不正確嗎？

參照這個文章，我改變我的標記如下：

<tbody>
    <tr *ngFor="let row of model">
      <ng-container *ngFor="let columnDataName of columnDataNames">
        <td *ngIf="modelConfig[columnDataName] && modelConfig[columnDataName].isVisible">
          <ng-container *ngIf="showRowTextBox && (columnDataName === conditionalInputName || columnDataName === conditionCheckBoxName); else otherColumns">
            <ng-container *ngIf="columnDataName === conditionalInputName">
              <input type="text" placeholder="Enter text here" [hidden]="!chkEnabled?.checked" (focusout)="onTextBoxFocusOut(row[primaryKeyColumnName], $event)"/>
            </ng-container>
            <ng-container *ngIf="columnDataName === conditionCheckBoxName">
              <input type="checkbox" #chkEnabled ngModel/>
            </ng-container>
          </ng-container>
          <ng-template #otherColumns>
            <ng-container *ngIf="modelConfig[columnDataName].isDate;">
              {{ row[columnDataName] | date:'d MMM yyyy' }}
            </ng-container>
            <ng-container *ngIf="modelConfig[columnDataName].isBoolean;">
              <tfg-toggle onText="Yes" offText="No" [disabled]="true" [value]="row[columnDataName]"></tfg-toggle>
            </ng-container>
            <ng-container *ngIf="!modelConfig[columnDataName].isBoolean && !modelConfig[columnDataName].isDate">
              {{ row[columnDataName] }}
            </ng-container>
          </ng-template>
        </td>
      </ng-container>
      <td *ngFor="let buttonColumnName of buttonColumnNames">
        <button (click)="executeButtonFunction(row[primaryKeyColumnName], buttonColumnName)" class="btn" [ngClass]="buttonColumnName === 'Delete' ? 'btn-danger' : 'btn-primary'">{{buttonColumnName}}</button>
      </td>
      <!-- <ng-container *ngIf="showRowTextBox">
        <td>
          <input type="text" placeholder="Enter text here" [hidden]="!chkEnabled.checked" (focusout)="onTextBoxFocusOut(row[primaryKeyColumnName], $event)"/>
        </td>
        <td>
          <input type="checkbox" [checked]="chkAll?.checked" #chkEnabled ngModel/>
        </td>
      </ng-container> -->
    </tr>
  </tbody>
