如何设置固定宽度<td>在一张桌子上？

在设计网页的过程中，对表格的需求是很正常的。 HTML 提供了

标签来构造表格并定义行和列，分别使用和

标签。

默认情况下，表格中的行和列的尺寸由浏览器以适合内容的方式自动调整。但是，可能存在需要固定列宽的情况。有多种方法可以固定

标签的宽度。其中一些如下所述：

使用宽度属性：

标签具有宽度属性来控制特定列的宽度。通过为该属性分配一个 0 到 100 之间的百分比数值（或者您可以使用像素格式）。我们可以将列宽限制为表格总宽度的百分比。 width 属性无效且已被拒绝，因此HTML5不再支持该属性。

使用 CSS：层叠样式表 (CSS) 被广泛用于装饰大尺寸的网页。通过使用 CSS，HTML 元素的样式很容易修改。为了固定 td标签的宽度，第 n 个子 CSS 用于设置 table 每一行中特定列的属性（由 n 的值确定）。

使用 col 标签并固定表格布局属性：如果在表格的每一行中都遵循相同类型的列属性，那么使用col标签来定义列的属性是一个好主意。如果第一次在 HTML 文档中写入 col标签并设置了它的属性，则这些 all 属性指的是表中每行的第一列，其中提到了它。同样，第二次使用 col标签并定义其属性会影响表格每行的第二列。此外，调整列内的长文本CSS 属性table-layout:fixed;使用。下面是实现。
