In CSS3, you can customize the table style by setting the pseudo element nth-child (n) to the element, where n can be a numerical value, keyword or formula

During the development process, we often encounter some table style requirements, such as making the first or last row in the table display different styles, or making the odd or even rows in the table display different background colors, etc. Etc., we can achieve these effects through the pseudo-class selector in CSS3. Next, we will introduce it in detail in the article, which has certain reference value. I hope it will be helpful to everyone.

##:nth-child(n) selector

:nth-child(n) selector is used to match elements that belong to its parent element The Nth child element, regardless of the data type of N, so we can set N to a number, keyword or formula

Basically all mainstream browsers support this attribute.

HTML code:

<style>
		table{
	font-size:16px;
	color:#333333;
	border-collapse: collapse;/*设置表格的边框是否被合并为一个单一的边框*/
		}
	th{
	border:1px solid #444;
	padding:25px;

	}
	td{
	border:1px solid #444;
	padding: 15px;
	}
	
	</style>
</head>
<body>
	<table>
		<tr>
			<th>示例一</th>
			<th>示例二</th>
			<th>示例三</th>
		</tr>
		<tr>
			<td>test1</td>
			<td>test1</td>
			<td>test1</td>
		</tr>
		<tr>
			<td>test2</td>
			<td>test2</td>
			<td>test2</td>
		</tr>
		<tr>
			<td>test3</td>
			<td>test3</td>
			<td>test3</td>
		</tr>
	</table>
