HTML tables can have different sizes for each column, row or the entire table.

Use the style attribute with the width or height properties to specify the size of a table, row or column.

HTML Table Width

To set the width of a table, add the style attribute to the <table> element:

Example

Set the width of the table to 100%:

<table style="width:100%"> <tr> <th>Firstname</th> <th>Lastname</th> <th>Age</th> </tr> <tr> <td>Jill</td> <td>Smith</td> <td>50</td> </tr> <tr> <td>Eve</td> <td>Jackson</td> <td>94</td> </tr></table> Try it Yourself »

Note: Using a percentage as the size unit for a width means how wide will this element be compared to its parent element, which in this case is the <body> element.

HTML Table Column Width

To set the size of a specific column, add the style attribute on a <th> or <td> element:

Example

Set the width of the first column to 70%:

<table style="width:100%"> <tr> <th style="width:70%">Firstname</th> <th>Lastname</th> <th>Age</th> </tr> <tr> <td>Jill</td> <td>Smith</td> <td>50</td> </tr> <tr> <td>Eve</td> <td>Jackson</td> <td>94</td> </tr></table> Try it Yourself »

HTML Table Row Height

To set the height of a specific row, add the style attribute on a table row element:

Example

Set the height of the second row to 200 pixels:

<table style="width:100%"> <tr> <th>Firstname</th> <th>Lastname</th> <th>Age</th> </tr> <tr style="height:200px"> <td>Jill</td> <td>Smith</td> <td>50</td> </tr> <tr> <td>Eve</td> <td>Jackson</td> <td>94</td> </tr></table> Try it Yourself » ❮ Previous Next ❯ +1 W3schools Pathfinder Track your progress - it's free!
