为什么有些列隐藏在 ngx-datatable 中？

Question

我尝试做一个 ngx-datatable，但最后一列被隐藏了。有人知道为什么吗？

<ngx-datatable #tableResponsive class="bootstrap core-bootstrap" [columnMode]="ColumnMode.force" [headerHeight]="50" [footerHeight]="50" [rowHeight]="50" [limit]="10" [rows]="rows" [scrollbarH]="true">
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Email" prop="email" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age" prop="age" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age" prop="age" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age" prop="age" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age" prop="age" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age" prop="age" >
              </ngx-datatable-column>
              <ngx-datatable-column name="Age1" prop="age" >
              </ngx-datatable-column>
</ngx-datatable>
