Tables are an essential part of web design, allowing you to organize and present data in a tabular format.
Introduction to HTML Tables
HTML tables are used to display data in rows and columns, similar to a spreadsheet. They are useful for presenting data in a structured format, making it easy to read and compare information.
Basic Structure of an HTML Table
The basic structure of an HTML table consists of the <table> element, along with the <tr>, <th>, and <td> elements for table rows, headers, and data cells, respectively.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Basic HTML Table</title>
</head>
<body>
<h2>Basic HTML Table</h2>
<table border="1">
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
<tr>
<td>John</td>
<td>Doe</td>
<td>30</td>
</tr>
<tr>
<td>Jane</td>
<td>Smith</td>
<td>25</td>
</tr>
</table>
</body>
</html>
Adding Headers, Footers, and Captions
You can enhance your table by adding headers (<thead>), footers (<tfoot>), and captions (<caption>).
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTML Table with Header, Footer, and Caption</title>
</head>
<body>
<h2>HTML Table with Header, Footer, and Caption</h2>
<table border="1">
<caption>Employee Data</caption>
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
</thead>
<tfoot>
<tr>
<td colspan="3">End of Data</td>
</tr>
</tfoot>
<tbody>
<tr>
<td>John</td>
<td>Doe</td>
<td>30</td>
</tr>
<tr>
<td>Jane</td>
<td>Smith</td>
<td>25</td>
</tr>
</tbody>
</table>
</body>
</html>
Merging Cells with colspan and rowspan
You can merge cells using the colspan and rowspan attributes to create more complex table structures.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>HTML Table with Merged Cells</title>
</head>
<body>
<h2>HTML Table with Merged Cells</h2>
<table border="1">
<tr>
<th>Product</th>
<th colspan="2">Details</th>
</tr>
<tr>
<td rowspan="2">Laptop</td>
<td>Brand</td>
<td>Price</td>
</tr>
<tr>
<td>Apple</td>
<td>$1200</td>
</tr>
</table>
</body>
</html>
Styling HTML Tables with CSS
CSS can be used to style HTML tables, making them more visually appealing and easier to read.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Styled HTML Table</title>
<style>
table {
width: 100%;
border-collapse: collapse;
}
th, td {
border: 1px solid #ddd;
padding: 8px;
}
th {
background-color: #f2f2f2;
text-align: left;
}
tr:nth-child(even) {
background-color: #f9f9f9;
}
tr:hover {
background-color: #ddd;
}
</style>
</head>
<body>
<h2>Styled HTML Table</h2>
<table>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
<tr>
<td>John</td>
<td>Doe</td>
<td>30</td>
</tr>
<tr>
<td>Jane</td>
<td>Smith</td>
<td>25</td>
</tr>
</table>
</body>
</html>
Advanced Features: Responsive Tables
Responsive tables adjust to different screen sizes, ensuring usability on mobile devices. This can be achieved using CSS media queries and responsive design techniques.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Responsive HTML Table</title>
<style>
table {
width: 100%;
border-collapse: collapse;
}
th, td {
border: 1px solid #ddd;
padding: 8px;
text-align: left;
}
th {
background-color: #f2f2f2;
}
tr:nth-child(even) {
background-color: #f9f9f9;
}
@media screen and (max-width: 600px) {
table, thead, tbody, th, td, tr {
display: block;
}
th {
display: none;
}
td {
display: block;
text-align: right;
padding-left: 50%;
position: relative;
}
td::before {
content: attr(data-label);
position: absolute;
left: 0;
width: 50%;
padding-left: 15px;
font-weight: bold;
text-align: left;
}
}
</style>
</head>
<body>
<h2>Responsive HTML Table</h2>
