</style>表格数据不显示是为什么
<p>根据提供的代码，表格数据不显示可能是因为注释掉了 <code>tableData</code> 的定义。需要将注释取消掉或者重新定义 <code>tableData</code>，并且确保 <code>tableData</code> 中的属性名与 <code>tablelist</code> 中的 <code>name</code> 对应。另外，<code>el-table-column</code> 中的 <code>prop</code> 属性应该绑定到 <code>item.name</code>，而不是字符串 '“{{ item.name }}”'。</p>
