Exploration of CSS table border properties: border-collapse and border-spacing

In web development, tables are a common element used to display and organize data. In order to make the table more readable and beautiful, we can use CSS to adjust the style of the table. When adjusting table styles, border-collapse and border-spacing are two very commonly used properties.

  1. border-collapse: Border merge

The border-collapse property is used to control whether the borders of the table are merged into a single border. It has two optional values:

  • collapse: Indicates that the borders are merged into a single border. It's the default value.
  • separate: Indicates that the borders remain separated.

The following is a sample code:

<style>
    table {
        border-collapse: collapse;
    }
    th, td {
        border: 1px solid black;
        padding: 10px;
    }
</style>

<table>
    <tr>
        <th>姓名</th>
        <th>年龄</th>
    </tr>
    <tr>
        <td>张三</td>
        <td>25</td>
    </tr>
    <tr>
        <td>李四</td>
        <td>30</td>
    </tr>
</table>

Run the above code, you can see that the borders in the table are merged into a single border line.

  1. border-spacing: border spacing

The border-spacing property is used to control the distance between the borders of the table. It can be used to set horizontal and vertical spacing, with the following syntax:

border-spacing: 水平间距 垂直间距;

Here is a sample code:

<style>
    table {
        border-collapse: separate;
        border-spacing: 10px;
    }
    th, td {
        border: 1px solid black;
        padding: 10px;
    }
</style>

<table>
    <tr>
        <th>姓名</th>
        <th>年龄</th>
    </tr>
    <tr>
        <td>张三</td>
        <td>25</td>
    </tr>
    <tr>
        <td>李四</td>
        <td>30</td>
    </tr>
</table>

Run the above code, you can see that 10 pixels are produced between the borders in the table Pitch.

To sum up, border-collapse and border-spacing are two important properties in CSS for adjusting table borders. border-collapse is used to control whether to merge table borders, and border-spacing is used to control the distance between borders. In practical applications, we can choose appropriate values ​​according to needs and optimize the style and readability of the table.
