如何为表格设置水平表头？

语法

以下是设置表格水平标题的语法：

<tr>
   <th> horizontal header1… </th>
   <th> horizontal header2… </th>
</tr>

Example 1

的中文翻译为：

示例 1

Now let us see an example program to set horizontal header for a table.

<!DOCTYPE html>
<html>
<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">
   <style>
      table,tr,th,td {
         border:1px solid black;
         padding: 20px;
      }
   </style>
</head>
<body>
   <h2>Tables in HTML</h2>
   <table style="width: 100%">
      <tr>
         <th >First Name </th>
         <th>Job role</th>
      </tr>
      <tr>
         <td ></td>
         <td ></td>
      </tr>
      <tr>
         <td ></td>
         <td ></td>
      </tr>
      <tr>
         <td></td>
         <td></td>
      </tr>
   </table>
</body>
</html>

On executing the above program, it will display a table with horizontal headers First Name and Job role.

Example 2

现在，在这个第二个示例中，我们尝试创建另一个具有水平标题“Name”、“Age”和“Technology”的3行示例 −

<!DOCTYPE html>
<html>
<head>
   <style>
      table, th, td {
         border: 1px solid black;
         width: 100px;
         height: 50px;
      }
   </style>
</head>
<body>
   <h1>Employee Details</h1>
   <table>
      <tr>
         <th>Name</th>
         <th>Age</th>
         <th>Technology</th>
      </tr>
      <tr>
         <td>Amit</td>
         <td>27</td>
         <td>Database</td>
      </tr>
      <tr>
         <td>Sachin</td>
         <td>34</td>
         <td>Marketing</td>
      </tr>
   </table>
</body>
</html>

Following is the output for the above example program.

Example 3

我们还可以为表格设置垂直标题。下面是一个示例，用于创建表格的垂直标题。

<!DOCTYPE html>
<html>
<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">
   <style>
      table,tr,th,td {
         border:1px solid black;
         padding: 20px;
      }
   </style>
</head>
<body>
   <table style="width: 100%">
      <tr>
         <th>First Name </th>
         <td></td>
         <td></td>
      </tr>
      <tr>
         <th>Last Name</th>
         <td ></td>
         <td></td>
      </tr>
      <tr>
         <th>Job role</th>
         <td ></td>
         <td></td>
      </tr>
   </table>
</body>
</html>

Following is the output for the above example program.
