Defines the attribute values for one or more columns in a table. You can only use this element inside a table or a colgroup.
为表格中的一个或多个列定义属性值。你只能在表格或colgroup里使用这个元素
In HTML the <col> tag has no end tag.
在HTML中<col>不需要结束标签
In XHTML the <col> tag must be properly closed.
在XHTML中<col>标签必须合理关闭
Note: The col element is an empty element that contains attributes only. To create columns, you must specify td elements within a tr element.
注意:col为空元素,它只能包含属性。你必须在tr元素里指定td元素才能建立列。
Tip: Use this element when you want to specify different attribute values to a column inside a colgroup. Without a col element a column will inherit all its attribute values from the colgroup.
提示:当你想要给在colgroup里的列指定不同的属性值时可以使用这个元素。当col元素不存在的时候列会继承所有来自colgroup里的属性。
