What is CSS cellpadding?

When learning CSS style design, you often encounter the cellpadding property. cellpadding is a CSS property used to set the padding of cells in HTML table elements. This article will detail the purpose, usage, and examples of cellpadding.

What is cellpadding

In HTML tables, each cell (<td>) displays a certain amount of space within it, which is called padding. The cellpadding property is used to set this padding for table cells, ensuring a certain distance between the cell content and the cell border.

How to Use CellPadding

The cellpadding attribute can be applied directly to the <table> tag or defined using CSS styles to define table padding. When applied directly to the <table> tag, the value of the cellpadding attribute applies to all cells in the table. When defined using CSS styles, different padding values can be applied to different tables.

Apply directly to `<table>` tag

<!DOCTYPE html> 
<html> 
<head> 
<style> 
table { 
cellpadding: 10px; /* Sets the table's padding to 10px */ 
} 
</style> 
</head> 
<body> 

<table border="1"> 
<tr> 
<td>Cell 1</td> 
<td>Cell 2</td> 
</tr> 
<tr> 
<td>Cell 3</td> 
<td>Cell 4</td> 
</tr> 
</table> 

</body> 
</html>

In the example above, we set the table’s padding to 10px by directly applying the cellpadding property.

CSS style definition

<!DOCTYPE html>
<html>
<head>
<style>
.table1 {
cellpadding: 5px; /* Set the table padding to 5px */
}

.table2 {
cellpadding: 15px; /* Set the table padding to 15px */
}

</style>
</head>
<body>

<table class="table1" border="1">
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
</tr>
<tr>
<td>Cell 3</td>
<td>Cell 4</td>
</tr> 
</table> 

<table class="table2" border="1"> 
<tr> 
<td>Cell A</td> 
<td>Cell B</td> 
</tr> 
<tr> 
<td>Cell C</td> 
<td>Cell D</td> 
</tr> 
</table> 

</body> 
</html>

In the above example, we defined two classes, table1 and table2, using CSS styles and setting different padding values for each.

Example Effect

Through the above example code, we can see the effect of different padding settings on a table. By adjusting the value of the cellpadding property, we can achieve different table display effects. Padding can make a table look more attractive and easier to read and understand.

Summary

cellpadding is a CSS property used to set the padding of table cells. By appropriately setting padding values, you can make table content clearer and more aesthetically pleasing. In actual development, properly setting the cellpadding property based on design requirements and aesthetics can improve the reading experience and user-friendliness of web pages.
