当我使用colspan时，表格宽度不起作用。我需要科尔斯潘。宽度尺寸为100px；或没有colspan底部源代码宽度大小的10％的作品。我该如何编辑？我可以问吗？请帮忙。
<link href="css/bootstrap.min.css" rel="stylesheet">
<style>
table {
table-layout: fixed;
word-wrap: break-word;
width: 30%;
}
</style>
</head>
<body>
<table>
<tr>
<td colspan="2">abc</td>
</tr>
<tr class="table table-bordered">
<td style="width: 10%;" /td>1</td>
<td style="width: 20%;" /td>2</td>
</tr>
</table>
