Mastering HTML Tables: Elements and Examples
HTML tables are powerful tools for organizing and displaying data in a structured format. In this article, we’ll explore the various elements of HTML tables and provide a comprehensive example.
Basic Table Structure:
The <table> element is the container for all other table elements. A table consists of rows ( <tr> ) and cells ( <td> for data cells , and <th> for header cells). The header cells typically contain labels for the columns or rows.
HTML Table Tag Example:
<!DOCTYPE html> <html> <head> <title>HTML Table Example</title> </head> <body> <table border="1"> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> </tr> <tr> <td>Data 1.1</td> <td>Data 1.2</td> <td>Data 1.3</td> </tr> <tr> <td>Data 2.1</td> <td>Data 2.2</td> <td>Data 2.3</td> </tr> </table> </body> </html>
Output Of Above Code :
Table Tag Elements:
1.<table> :
The container for the entire table.
2.<tr> :
Defines a table row. Contains one or more cells.
3.<th> :
Defines a header cell. Typically used in the first row or first column to label the data.
4. <td> :
Defines a data cell. Contains the actual data of the table.
Attributes:
border : Specifies the border width of the table. It is commonly used for styling purposes, although CSS is recommended for more control.
Table Example:
Let’s break down the example above:
<table border="1"> <tr> <th>Header 1</th> <th>Header 2</th> <th>Header 3</th> </tr> <tr> <td>Data 1.1</td> <td>Data 1.2</td> <td>Data 1.3</td> </tr> <tr> <td>Data 2.1</td> <td>Data 2.2</td> <td>Data 2.3</td> </tr> </table>
– The <table> element is the container for the entire table.
– Each <tr> represents a row. The first row contains <th> for headers, and subsequent rows contain <td> for data.
– The border=”1″ attribute adds a border to the table for visual clarity (Note: styling with CSS is recommended).
Additional Attributes and Styling:
1.colspan and rowspan :
These attributes allow a cell to span multiple columns or rows.
<td colspan="2">Spanning two columns</td>
2. CSS Styling:
Use CSS for more advanced styling and layout control.
For example:
table {
width: 100%;
border-collapse: collapse;
}
th, td {
border: 1px solid black;
padding: 8px;
text-align: left;
}
This CSS ensures a clean, border-collapse layout with proper padding for cells.
