A Complete Guide - HTML Creating Tables with the table Tag
HTML Creating Tables with the <table>
Tag
Basic Structure of an HTML Table
An HTML table is constructed using a series of nested tags that define its structure. Here’s the basic structure:
<table>
: This tag encloses the entire table.<thead>
: (Optional) Encloses the header section of the table.<tr>
: Encloses a row of header cells.<th>
: Defines a header cell in a table.
<tbody>
: (Optional) Encloses the body section of the table.<tr>
: Encloses a row of data cells.<td>
: Defines a standard data cell.
<tfoot>
: (Optional) Encloses the footer section of the table.<tr>
: Encloses a row of footer cells.<td>
or<th>
: Usually, footer cells are defined as data or header cells.
Example:
<table> <thead> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> </tr> </thead> <tbody> <tr> <td>Row 1, Cell 1</td> <td>Row 1, Cell 2</td> <td>Row 1, Cell 3</td> </tr> <tr> <td>Row 2, Cell 1</td> <td>Row 2, Cell 2</td> <td>Row 2, Cell 3</td> </tr> </tbody>
</table>
Key Attributes and Tags
border
: Although not recommended for modern web design (instead, CSS should be used), this attribute defines the width of the table border in pixels.cellpadding
: Defines the space between cell content and cell borders.cellspacing
: Defines the space between each cell.colspan
androwspan
:colspan
specifies the number of columns a cell should span.rowspan
specifies the number of rows a cell should span.
Example:
<table> <tr> <th colspan="2">Header 1 & 2</th> <th>Header 3</th> </tr> <tr> <td rowspan="2">Row 1 & 2, Cell 1</td> <td>Row 1, Cell 2</td> <td>Row 1, Cell 3</td> </tr> <tr> <td>Row 2, Cell 2</td> <td>Row 2, Cell 3</td> </tr>
</table>
Styling Tables with CSS
CSS is the preferred method for styling tables to ensure a clean separation between content and presentation.
Basic Styling:
table { width: 100%; border-collapse: collapse; /* Removes spaces between cells */ } th, td { padding: 10px; border: 1px solid black; text-align: left; /* Default alignment for data cells */ } th { background-color: #f2f2f2; }
Hover Effects:
tr:hover { background-color: #f1f1f1; }
Zebra Striping:
tr:nth-child(even) { background-color: #f2f2f2; }
Accessibility Considerations
To ensure your tables are accessible, keep the following guidelines in mind:
- Use logical table structure.
- Avoid using tables for layout purposes.
- Use
<caption>
to provide a summary of the table. - Use
<scope>
attribute for better association between headers and data cells (e.g.,<th scope="col">
or<th scope="row">
).

Step-by-Step Guide: How to Implement HTML Creating Tables with the table Tag
Example 1: Basic HTML Table
Step 1: Start with a basic HTML document structure.
<!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> </body>
</html>
Step 2: Inside the <body>
tag, add the <table>
element.
<table>
</table>
Step 3: To create rows within the table, use <tr>
(table row) elements.
<table> <tr> </tr> <tr> </tr>
</table>
Step 4: Within each <tr>
, add <th>
(table header) or <td>
(table data) elements to define the cells. Use <th>
for headers and <td>
for regular data.
<table> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr>
</table>
Complete code for Example 1:
<!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> <table> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr>
</table> </body>
</html>
Example 2: Adding Borders and Styling
Step 1: Start with a basic table as in Example 1.
<table> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr>
</table>
Step 2: Add the border
attribute to the <table>
tag to make the borders visible.
<table border="1">
Step 3: You can style the table further using CSS within a <style>
block or an external stylesheet. Here’s an example using internal CSS.
<style> table { width: 50%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: left; } th { background-color: #f2f2f2; }
</style>
Complete code for Example 2:
<!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: 50%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: left; } th { background-color: #f2f2f2; } </style>
</head>
<body> <table> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr>
</table> </body>
</html>
Example 3: Spanning Multiple Columns and Rows
Step 1: Start with a basic table again.
<table> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr>
</table>
Step 2: Make the first row header span across all columns to create a title row. Use the colspan
attribute.
<tr> <th colspan="3">Person Information</th>
</tr>
Step 3: For multiple rows, you can use the rowspan
attribute. Add another row where the "Name" spans two rows.
<tr> <td rowspan="2">John Doe</td> <td>30</td> <td>New York</td>
</tr>
<tr> <!-- Name cell is empty because it's spanned --> <td>Jane Smith</td> <td>Los Angeles</td>
</tr>
Complete code for Example 3:
<!DOCTYPE html>
<html lang="en">
<head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Spanning HTML Table</title> <style> table { width: 50%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: left; } th { background-color: #f2f2f2; } </style>
</head>
<body> <table> <tr> <th colspan="3">Person Information</th> </tr> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> <tr> <td rowspan="2">John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <!-- Name cell is empty because it's spanned --> <td>Jane Smith</td> <td>Los Angeles</td> </tr>
</table> </body>
</html>
Example 4: Caption and Group Headers
Step 1: Add a caption using the <caption>
tag inside the <table>
.
<table> <caption>List of Employees</caption>
</table>
Step 2: Group table headers into sections using <thead>
, <tbody>
, and <tfoot>
.
<table> <caption>List of Employees</caption> <thead> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> </thead> <tbody> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr> </tbody>
</table>
Step 3: Add a footer section using the <tfoot>
tag. This could be used to summarize the table data or provide additional information.
<table> <caption>List of Employees</caption> <thead> <tr> <th>Name</th> <th>Age</th> <th>City</th> </tr> </thead> <tbody> <tr> <td>John Doe</td> <td>30</td> <td>New York</td> </tr> <tr> <td>Jane Smith</td> <td>25</td> <td>Los Angeles</td> </tr> </tbody> <tfoot> <tr> <td>Total</td> <td>55</td> <td>-</td> </tr> </tfoot>
</table>
