本篇文章主要的介绍了关于HTML tfoot标签的定义和详细的使用方法实例，让大家都能一下就能看出来HTML tfoot标签的具体的用法，大家可以跟着上面的说的去实践，所有的软件方面的能力都是需要不断的敲代码练习出来的。好了，说多了，开始我们今天的这篇文章吧。

html tfoot标签的定义和用法：

在html中，
标签是用来组合html表格的页脚内容，通常与标签和标签一起使用，分别用来规定表格的页脚、表头和主体。
标签必须是标签元素的子元素，应用在标签和标签之后，标签之前。

标签、
标签和标签默认情况下不会影响表格的布局，通常使用css来定义表格的样式。
注释：如果您使用 thead、tfoot 以及 tbody 元素，您就必须使用全部的元素。它们的出现次序是：thead、tfoot、tbody，这样浏览器就可以在收到所有数据前呈现页脚了。您必须在 table 元素内部使用这些标签。
提示：在默认情况下这些元素不会影响到表格的布局。不过，您可以使用 CSS 使这些元素改变表格的外观。
html tfoot标签的详细描述：
thead、tfoot 以及 tbody 元素使您有能力对表格中的行进行分组。当您创建某个表格时，您也许希望拥有一个标题行，一些带有数据的行，以及位于底部的一个总计行。这种划分使浏览器有能力支持独立于表格标题和页脚的表格正文滚动。当长的表格被打印时，表格的表头和页脚可被打印在包含表格数据的每张页面上。
html tfoot标签的用法介绍：
tbody，thead，tfoot都是table的子标签，很显然他们分别是“表体”，“表头”，“表尾”。他们的显示顺序是从头到尾的，thead先于tbody，tbody先于tfoot，这要求我们在设置这些标签时，thead在tbody前出现，tbody在tfoot前出现，一个table里面允许多个tbody。这些标签可以是一个大表分块显示，即先显示一块，再显示后面的块，这里的块是以表格中“行”为单位的，即tbody标签的下级标签是tr，这样就可以使浏览者先看到一部分完整的信息。虽然完整显示一个页面的时间是一样的，但是这更加人性化。
HTML
标签用法实例
带有 thead、tbody 以及 tfoot 元素的 HTML 表格：
<table border="1"> <thead> <tr> <th>Month</th> <th>Savings</th> </tr> </thead> <tfoot> <tr> <td>Sum</td> <td>$180</td> </tr> </tfoot> <tbody> <tr> <td>January</td> <td>$100</td> </tr> <tr> <td>February</td> <td>$80</td> </tr> </tbody> </table>
标签基本属性（html5已经不支持）

align right：

元素中内容的对齐方式（值：left、center、justify、char）。

char：

元素中内容根据哪个字符来对进行文本对齐(值：character)。

charoff:

元素中内容的第一个对齐字符的偏移量(值：number)。

valign：

元素中内容的垂直对齐方式(值：top、middle、bottom、baseline)。
标签支持html全局属性和html事件属性
html tfoot标签的格式：
<tfoot> <tr> <td>......</td> </tr> ...... </tfoot>
html tfoot标签的用法实例：
<!doctype html> <html> <head> <meta charset="UTF-8"> <title>html< tbody>标签笔记</title> </head> <body> <table border="1"> <thead> <tr> <th>thead1</th> <th>thead2</th> <th>thead3</th> </tr> </thead> <tfoot> <tr> <td>tfoot1</td> <td>tfoot2</td> <td>tfoot3</td> </tr> </tfoot> <tbody> <tr> <td>tbody1</td> <td>tbody2</td> <td>tbody3</td> </tr> </tbody> </table> </body> </html>
