HTML Table Alternate Row Color
The presentation of alternate-colored rows in HTML tables can contribute to increased readability and visual appeal. This technique produces a checkered pattern using another color and styling background color for every other row. You will make it easier to distinguish rows from one another, especially for users who deal with tables informatics large tables that are meant to accommodate a lot of data.
This approach can improve the overall customer experience, as well as contribute to higher visibility of the data within the table to lessen the perception of the table itself. This is normally done using CSS by checking even and odd rows and setting the background color for each of them in an isolated manner. This technique is often used in web applications to improve how tabled information is displayed.
Implementation
In an HTML table, you can use CSS to design the even and odd rows differently in order to create alternate row colors. Observe this simple example:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="styles.css">
</head>
<body>
<table>
<tr>
<th>Header 1</th>
<th>Header 2</th>
<th>Header 3</th>
</tr>
<tr>
<td>Row 1, Column 1</td>
<td>Row 1, Column 2</td>
<td>Row 1, Column 3</td>
</tr>
<tr>
<td>Row 2, Column 1</td>
<td>Row 2, Column 2</td>
<td>Row 2, Column 3</td>
</tr>
<!-- Add more rows as needed -->
</table>
</body>
</html>
CSS:
table {
border-collapse: collapse;
width: 100%;
}
th, td {
padding: 8px;
text-align: left;
border-bottom: 1px solid #ddd;
}
tr:nth-child(even) {
background-color: #f2f2f2;
}
th {
background-color: #4CAF50;
color: white;
}
Example 1:
<!DOCTYPE html>
<html>
<head>
<style>
<!DOCTYPE html>

<style>

border-collapse: collapse;
width: 100%;
}
th, td {
te
table {
border-collapse: collapse;
width: 100%;
}
th, td {
text-align: left;
padding: 8px;
}
tr:nth-child(even) {
background-color: black;
color: white;
}
</style>
</head>
<body>
<table>
<tr>
<th> a1 </th>
<th> a2 </th>
<th> a3 </th>
<th> a4 </th>
</tr>
<tr>
<td> a1 </td>
<td> a2 </td>
<td> a3 </td>
<td> a4 </td>
</tr>
<tr>
<td> a1 </td>
<td> a2 </td>
<td> a3 </td>
<td> a4 </td>
</tr>
<tr>
<td> a1 </td>
<td> a2 </td>
<td> a3 </td>
<td> a4 </td>
</tr>
<tr>
<td> a1 </td>
<td> a2 </td>
<td> a3 </td>
<td> a4 </td>
</tr>
</table>
</body>
</html>
Output:
