中的文本对齐方式。标签。它可以使用以下值。
但是，HTML 5 不支持此属性。
2.背景
我们可以使用 style 标签中的 background 属性来设置行的背景。让我们看一下下面的示例。
代码：
<!DOCTYPE html>
<html>
<head>
<title>This is a table example</title>
<style>
th, td {
padding : 10px;
border : 1px solid #666;
}
</style>
</head>
<body>
<table style=" width:80%; margin : 30px auto; border-collapse : collapse;">
<tr>
<th> Sr. No. </th>
<th> Popular programming languages </th>
<th> Description </th>
</tr>
<tr style="background : #00ff3787"> // here we are setting the back ground color to #00ff3787
<td> 1 </td>
<td> Java </td>
<td> Java has been holding position 1 or 2 for the world’s most popular languages since it’s inception. It was created in mid 90s and since then many large and small companies have adopted it for developing desktop and web applications</td>
</tr>
<tr>
<td> 2</td>
<td> C </td>
<td>C is a popular language for cars, sensors and embedded systems. It has been one of the top most popular languages mainly due to its universal compatibility</td>
</tr>
<tr>
<td>3</td>
<td>Python</td>
<td>Python is very popular in today’s era specially since it support quick development of application based on machine learning, big data and AI.</td>
</tr>
</table>
</body>
</html>
上述代码在浏览器窗口中的输出如下，其中第一行的背景颜色已更改为绿色：
3.颜色
我们可以通过使用 tr 标签中的 color 属性来操作箭头中文本的颜色。让我们将其中一行的字体颜色更改为灰色。
代码：
<!DOCTYPE html>
<html>
<head>
<title>This is an example of HTML table</title>
<style>
th, td {
padding : 10px;
border : 1px solid #666;
}
</style>
</head>
<body>
<table style=" width:80%; margin : 30px auto; border-collapse : collapse;">
<tr>
<th> Sr. No. </th>
<th> Popular programming languages in 2019 </th>
<th> Description </th>
</tr>
<tr style="color : grey"> // here we are setting the font color to grey
<td> 1 </td>
<td> Java </td>
<td> Java has been holding position 1 or 2 for the world’s most popular languages since it’s inception. It was created in mid 90s and since then many large and small companies have adopted it for developing desktop and web applications</td>
</tr>
<tr>
<td> 2</td>
<td> C </td>
<td>C is a popular language for cars, sensors and embedded systems. It has been one of the top most popular languages mainly due to its universal compatibility</td>
</tr>
<tr>
<td>3</td>
<td>Python</td>
<td>Python is very popular in today’s era specially since it support quick development of application based on machine learning, big data and AI.</td>
</tr>
</table>
</body>
</html>
上述代码在浏览器窗口中的输出如下所示，我们可以发现应用于表格第一行的字体颜色：
结论
如上所示，我们可以使用 HTML 表和 tr 元素来定义和表示结构化数据。我们可以自定义同一个表中的不同行来更改行的样式。我们还可以使用 th 和 td 来定义表头和标准表数据。我们可以进一步自定义一行的字体颜色、字体大小、字体家族、字体装饰和背景颜色。
