html表格居中代码,第1张

1、首先打开vscode编辑器，新建一个html文档，里面写入一个外层的div，再加入一行table表格：

2、然后在上方的style标签中加入css样式，设置table标签的样式，table的元素具有长度自适应性，其长度根据其内文本长度决定，只要设置margin属性，让左右设置为auto就回自动分配剩余空间，也就是元素两侧的区域各占50%，那么元素就左右居中了：

3、最后打开浏览器就可以看到居中的一行表格了：

html中让表格在浏览器中左右居中，可以设置表格的align属性

align有三个属性：

1、居中：center；

2、靠左：left；

3、靠右：right。

html中是没办法实现上下居中的，如果设置上下居中，需要通过js程序来设置。

左右居中代码如下：
