1. Form properties
| Form properties | usage |
| border |
Represents the thickness of the table border width height table width and height |
| align |
table tr td set horizontal alignment default value left center right |
| cellspacing |
cell to cell distance |
| cellpadding |
Cell text to cell border distance |
| bgcolor |
Table background color table tr td can be used |
| background |
You can set a background image for the table |
| valign |
Set vertical alignment top middle (default) bottom |
Merge table cell borders and style the table
border-collapse: collapse;Two, table table sample code

The achieved effect diagram is as follows, you can operate according to the properties of the table
3. The problem of cell merging
Merge across rows rowspan='number' Merge across columns colspan='number'
Code example before merging:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
<table border="1" cellspacing="0" align="center" width="300px" height="300px">
<!-- ctrl + enter 表示换行 -->
<!-- 跨行合并 rowspan='number' 跨列合并 colspan='number' -->
<tr>
<td>11</td>
<td>12</td>
<td>13</td>
<!-- 跨多行列合并 -->
<td>14</td>
<td>15</td>
<td>16</td>
</tr>
<tr>
<td>21</td>
<td>22</td>
<td>23</td>
<td>24</td>
<td>25</td>
<td>26</td>
</tr>
<tr>
<td>31</td>
<td>32</td>
<td>33</td>
<td>34</td>
<td>35</td>
<td>36</td>
</tr>
</table>
</body>
</html>
The merged effect diagram is as follows:
The merged code is as follows:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>
</head>
<body>
<table border="1" cellspacing="0" align="center" width="300px" height="300px">
<!-- ctrl + enter 表示换行 -->
<!-- 跨行合并 rowspan='number' 跨列合并 colspan='number' -->
<tr>
<td colspan="2">11</td>
<!-- <td>12</td> -->
<td>13</td>
<!-- 跨多行列合并 -->
<td colspan="3" rowspan="2">14</td>
<!-- <td>15</td>
<td>16</td> -->
</tr>
<tr>

<td rowspan="2">22</td>
<td>23</td>
<!-- <td>24</td> -->
<!-- <td>25</td>
