                  <tr align="center" width="100" >
                     <td>1</td>
                     <td colspan="2">占两列</td>    <!--当colspan="2"表示在同一行中，两列并一列，那么在它下面少写一个<td></td>标签-->
                     <!-- 删除掉此<td></td> -->
                     <td>2</td>
                 </tr>

                 <tr   align="center" width="100">

Note

: When you enter different content in each cell of the table, your content will change with different lengths. If you want each cell to maintain There are two ways to make the same size: 1; For example, when the total height of your table is 400 and you set 4 rows, then add attributes to each tag: hight=100; which is equivalent to even distribution, and use the same width for the same width. method. 2: It will be simpler than the first one, which is to set the css style and fix the size of tr and td

2: List tag

<!DOCTYPE html>
<html>
    <head>
    <title>列表标签</title>
