The HTML <td> tag stands for Table Data, and it is used to define individual cells in a table row. These cells can hold various types of content, including text, images, links, and other HTML elements. The <td> tag is a fundamental part of building HTML tables, ensuring that data is displayed in a structured and organized manner.
HTML tables are widely used for displaying tabular data, making the <td> tag essential for web developers to create meaningful and readable tables. The <td> tag is used within the <tr> (table row) element to define the actual data content for each table row. The tag helps improve the overall presentation of data on the web.
Syntax of the <td> Tag
The basic syntax of the <td> tag is straightforward and is used inside the <table> and <tr> tags. Here’s the standard syntax:
<td>Cell Content</td>
The <td> element can contain any valid HTML content, such as text, images, links, or even other HTML elements like lists.
<table>
<tr>
<td>Row 1, Cell 1</td>
<td>Row 1, Cell 2</td>
</tr>
<tr>
<td>Row 2, Cell 1</td>
<td>Row 2, Cell 2</td>
</tr>
</table>
In this example, each <td> tag defines a cell within the table structure.
Attributes of the <td> Tag
The HTML <td> tag supports several attributes that can modify the appearance and behavior of the table data cells. Here’s a list of common attributes:
Attribute | Description |
---|---|
colspan | Specifies how many columns the cell should span. |
rowspan | Specifies how many rows the cell should span. |
headers | Associates the cell with header cells in the table, improving accessibility. |
align | Specifies the alignment of content inside the cell (deprecated in HTML5). |
valign | Specifies vertical alignment of the content (deprecated in HTML5). |
style | Allows inline CSS styling to customize the appearance of the table cell. |
bgcolor | Specifies the background color of the cell (deprecated in HTML5, use CSS instead). |
Example of Common Attributes
Colspan Example
<table>
<tr>
<td colspan="2">This cell spans 2 columns</td>
</tr>
<tr>
<td>Cell 1</td>
<td>Cell 2</td>
</tr>
</table>
Rowspan Example
<table>
<tr>
<td rowspan="2">This cell spans 2 rows</td>
<td>Cell 1</td>
</tr>
<tr>
<td>Cell 2</td>
</tr>
</table>
Examples of HTML <td> Tag
Example 1: Basic Table with Data Cells.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Basic Table Example</title>
</head>
<body>
<table border="1">
<tr>
<td>First Name</td>
<td>Last Name</td>
</tr>
<tr>
<td>John</td>
<td>Doe</td>
</tr>
<tr>
<td>Jane</td>
<td>Smith</td>
</tr>
</table>
</body>
</html>
In this example, each <td> tag represents a table cell containing text such as "First Name," "Last Name," and other data.
Example 2: Using Colspan and Rowspan in Table Data Cells
<!DOCTYPE html>
<html lang="en">
<head>
<title>Colspan and Rowspan Example</title>
</head>
<body>
<table border="1">
<tr>
<td colspan="2">This cell spans 2 columns</td>
</tr>
<tr>
<td rowspan="2">This cell spans 2 rows</td>
<td>Cell 1</td>
</tr>
<tr>
<td>Cell 2</td>
</tr>
</table>
</body>
</html>
This example illustrates how the colspan and rowspan attributes modify the table structure by spanning cells across multiple rows and columns.
