HTML table

Tables are very common in our daily lives, but how to output tables in our web pages? The

<table> tag defines an HTML table.

A simple HTML table consists of the table element and one or more tr, th, or td elements.

tr Element defines table row, th # The ## element defines the header, and the td element defines the table unit.

Let us make the simplest form

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php.cn</title>
</head>
<body>
<table border="1" cellspacing="0" cellpadding="10">
    <tr>
        <td>1月份</td>
        <td>￥100</td>
    </tr>
    <tr>
        <td>二月份</td>
        <td>￥200</td>
    </tr>
</table>
</body>
</html>

Program running results:

cellspacing, the distance between cells

cellpadding , the distance between the text and the cell border is in pixels

border Add a border to the text Set the border to border=0 and the table will not display the border

The above three attribute values can be set by yourself according to your own requirements

HTML table header

The header of the table is defined using the <th> tag.

Most browsers will display the header as bold, centered text:

Example

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php.cn</title>
</head>
<body>
<table border="1" cellspacing="0" cellpadding="10">
    <th>月份</th>
    <th>金额</th>
    <tr>
        <td>1月份</td>
        <td>￥100</td>
    </tr>
    <tr>
        <td>二月份</td>
        <td>￥200</td>
    </tr>
</table>
</body>
</html>

Program running result:

# colspan and rowspan

#By adding colspan and rowspan attributes to the <td> tag , you can merge cells horizontally and vertically

Instance

Before merging

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php.cn</title>
</head>
<body>
<table border="1" cellspacing="0" cellpadding="20">
    <tr>
        <td>单元格</td>
        <td>单元格</td>
        <td>单元格</td>
    </tr>
    <tr>
        <td>单元格</td>
        <td>单元格</td>
        <td>单元格</td>
    </tr>
    <tr>
        <td>单元格</td>
        <td>单元格</td>
        <td>单元格</td>
    </tr>
</table>
</body>
</html>

Program running result:

After merging

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php.cn</title>
</head>
<body>
<table border="1" cellspacing="0" cellpadding="20">
    <tr>
        <td colspan="2">单元格</td>
        <td>单元格</td>
    </tr>
    <tr>
        <td rowspan="2">单元格</td>
        <td>单元格</td>
        <td rowspan="2">单元格</td>
    </tr>
    <tr>
        <td>单元格</td>
    </tr>
</table>
</body>
</html>

##More Multiple instances

This example demonstrates a table without borders.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>php.cn</title>
</head>
<body>
<h4>这个表格没有边框:</h4>
<table>
    <tr>
        <td>200</td>
        <td>300</td>
    </tr>
    <tr>
        <td>500</td>
        <td>600</td>
    </tr>
</table>
<h4>这个表格没有边框:</h4>
<table border="0">
    <tr>
        <td>200</td>
        <td>300</td>
    </tr>
    <tr>
        <td>500</td>
        <td>600</td>
    </tr>
</table>
</body>

<body>
<table border="1">
    <tr>
        <td>
            <p>这是一个段落</p>
            <p>这是另一个段落</p>

        <td>这个单元格包含一个表格:
            <table border="1">
                <tr>
                    <td>A</td>
                    <td>B</td>
                </tr>
                <tr>
                    <td>C</td>
                    <td>D</td>
                </tr>
            </table>
        </td>
    </tr>
    <tr>
        <td>这个单元格包含一个列表
            <ul>
                <li>apples</li>

                <li>pineapples</li>
            </ul>
        </td>
        <td>HELLO</td>
    </tr>
</table>
</body>
</html>
