HTML table

A table is actually a lot of small cells, and these small cells are arranged in an orderly manner. They have many rows and columns. These things composed of many rows and columns are called tables, and tables are defined by the

tag. The rows in the
tag are the tags, and the columns are the
tags. Rows must be defined before columns can be defined. Because in html, each column is in a row.

The following table summarizes some commonly used tags:

below the above comment are written anyway. A very small table will appear, but the text written in will not be displayed

So in HTML, writing a table must be written line by line.

The tag contains
表格 描述
定义表格
定义表格标题
定义表格的表头
定义表格的行
定义表格的单元
定义表格的页眉
定义表格的主体
定义表格的页脚
定义表格的列属性

First define a simple table:

You can see it after running 

<!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>        <table border="1">            <tr>                <td>水果</td>                <td>水果</td>                <td>水果</td>            </tr>    <!-- 下面将td与tr反正写了，是不会构成表的 -->            <td>                <tr>asd</tr>                <tr>asd</tr>                <tr>asd</tr>                <tr>asd</tr>            </td>        </table>    </body></html>

As you can see, the

and

Table without borders

A table without borders is actually in the

tag without adding Property border. The border attribute represents the border of the table. If no attribute is added, the default border="0" will be used. However, if there is no border, sometimes you will not be able to tell that it is a table. So sometimes a 1-pixel border is set for border="1px". Temporarily remove the border attribute and complete a table without borders 

<!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>        <table>            <tr>                <td>呵呵</td>                <td>哈哈</td>                <td>嘻嘻</td>            </tr>            <tr>                <td>嘿嘿</td>                <td>嘎嘎</td>                <td>噗噗</td>            </tr>            <tr>                <td>啊啊</td>                <td>哦哦</td>                <td>噢噢</td>            </tr>        </table>    </body></html>


in the table The header

You can also add a header to the table, using the

tag. For the sake of better appearance, we still add the border: 

<!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>        <table border="1">            <tr>                <th>人物</th>                <th>介绍</th>                <th>产品</th>            </tr>            <tr>                <td>史蒂夫&middot;保罗&middot;乔布斯</td>                <td>苹果CEO</td>                <td>Apple系列</td>            </tr>            <tr>                <td>丹尼斯&middot;里奇</td>                <td>C语言之父</td>                <td>C语言</td>            </tr>            <tr>                <td>比尔&middot;盖茨</td>                <td>微软CEO</td>                <td>Windows系统</td>            </tr>        </table>    </body></html>

You can also set the margins within the table The cellpadding attribute
can also set the cell margins cellspacing attribute 

<table border="1" cellpadding="10" cellspacing="10">    <tr>        <td>xxx</td>    </tr></table>


Table with title

I am the header
tag, The tag is also in the 

<table border="1" cellpadding="10" cellspacing="10">            <caption>xxx表</caption>            <tr>                <td>xxx</td>            </tr></table>

The color bgcolor attribute in the table

<table border="1" bgcolor="red">    <tr>        <td>xxx</td>    </tr></table>


The align attributes of cell content arrangement are center, left, right

<table border="1" align="center">    <caption>xxx表</caption>    <tr>        <td>xxx</td>    </tr></table>

Colspan attribute of cells across rows and columns, to be precise, merged cells 

<table border="1">    <caption>xxx表</caption>    <tr>        <td colspan="2">xxx</td>        <td>xxx</td>    </tr>    <tr>        <td>xxx</td>        <td>xxx</td>        <td>xxx</td>    </tr></table>

HTML list

A list is just like the titles in word, counting down.

The subscripts are tags that control the title

标签 描述
    		有序列表
      		无序列表
    		• 列表项
      		列表
      		列表项
      		描述

       

      这些列表还分有序列表，无序列表和自定义列表。

      无序列表

             

        、

      •         属性：disc：实体圆、circle：空心圆、square：实体方块

        有序列表

               

          、

        1.         属性：A、a、l、i、start

          <!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>    <!-- 有序列表默认是数字往下计数的 -->        <ol>            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    <!-- 定义A，就是按照大写字母来计数的，当然了，不能直接定义B，它不是不会从B开始数的 -->        <ol type="A">            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    <!-- 定义a，就是安装小写字母开始计数的 -->        <ol type="a">            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    <!-- 定义I，就是按照大写罗马数字计数的 -->        <ol type="I">            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    <!-- 定义i，就是按照大写罗马数字计数的 -->        <ol type="i">            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    <!-- start属性，就是按照从多少数来计数，比如我想从3开始计数。start属性只能定义数字，不支持英文字母哦。 -->        <ol start="3">            <li>我是第一个</li>            <li>我是第二个</li>            <li>我是第三个</li>        </ol>    </body></html>

            、

          1. 嵌套列表就是有序列表套无序列表，无序套有序的呗。

            <!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>        <ol>            <li>人物</li>            <ul>                <li>斯蒂芬&middot;保罗&middot;乔布斯</li>                <li>丹尼斯&middot;里奇</li>                <li>比尔&middot;盖茨</li>            </ul>                        <li>动物</li>            <ul>                <li>猫</li>                <li>狗</li>                <li>熊</li>            </ul>        </ol>                </body></html>

            自定义的列表，就是没有有序、无序的点。后期可以用CSS样式来加工修改。也是比较常用的操作

            <!DOCTYPE html><html>    <head>        <title></title>        <meta charset="utf-8">    </head>    <body>        <dl>            <li>我是标题</li>            <dt>                <dd>我是正文，我必须长长长长长长长长长长长长长长长长长长长长长长长长长长长长长长</dd>            </dt>        </dl>                </body></html>
