我需要增加列宽，我试过 width-%,PX,rem 但这不起作用。如果表格的列数较少，我可以增加列宽，但在我的场景中，如果我的列数超过 15 列，则无法更改宽度。

<div class="table-responsive">
<table class="table">
  <thead>
    <tr>

<th scope="col">#</th><th scope="col">#</th>

      <th scope="col" style="width: 500px;">Heading heading'</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

      <th scope="col">Heading</th><th scope="col">Heading</th>

我尝试运行我的 Nestjstutorial 应用程序，显示以下错误。我的后端连接到 PostgreSQL 数据库。
