Question

我正在使用旧的AngularJS材质设计数据表，想知道如何调整列宽。

https://github.com/daniel-nagy/md-data-table

例如，如果我想将演示中的“ fat”列更改为固定宽度40px，我将如何处理？

固定填充似乎是主要问题。

table.md-table.md-row-select td.md-cell:nth-child(n+3):nth-last-child(n+2), table.md-table.md-row-select th.md-column:nth-child(n+3):nth-last-child(n+2) {
    padding: 0 56px 0 0;
}

Answer 1

您可以使用以下CSS类。

.width-override{
  width:40px !important;
  padding:0px !important;
}

您将需要像这样将其添加到相应列的th和td标签中。

<th md-column md-numeric md-order-by="fat.value" class="width-override"><span>Fat (g)</span></th>

<td md-cell class="width-override">{{dessert.fat.value | number: 2}}</td>

请查看以下示例！

注意：内容的宽度为56px，因此列的宽度为该宽度，您可能希望使用相同的宽度，因为我们不想将内容剪切到列中。
