Ever struggled with cramped tables on your website? This blog explores how proper cell spacing and padding transform table layouts, enhancing readability and design. Discover practical CSS techniques and design tips for creating visually balanced, responsive HTML tables.
Tables are a go-to element for presenting structured data on websites. But the way space is handled inside and between cells can completely change how a table looks and feels.
Have you ever looked at a table and felt it seemed too cramped or awkwardly spaced?
That’s often because the spacing between cells or the padding inside them hasn’t been set correctly.
This blog will walk you through practical, modern, and advanced ways to control spacing in HTML tables . We’ll talk about the differences, show working code, and explain CSS-based methods that work better for responsive designs. We will also touch on design principles that make your tables visually balanced.
Before adjusting spacing, it’s important to understand the difference between the two main spacing concepts. Many people confuse cellpadding and cellspacing, but they serve completely different purposes.
Think of it like a building floor plan:
Padding is like the space between the furniture and the walls inside a single room.Spacing is like the hallway distance between two rooms.
When you add cell padding, the content inside each table cell gets breathing space. Without it, text touches the borders and becomes harder to read. Padding can also help when you are working with data tables that have a lot of numbers, since the extra space prevents the values from looking cramped together.
Here’s an example:
1 2<!DOCTYPE html> 3<html> 4<head> 5 <meta charset="UTF-8"> 6 <title>Table with Cellpadding Example</title> 7 <style> 8 table, td { 9 border: 1px solid black; 10 } 11 </style> 12</head> 13<body> 14 15<table cellpadding="10"> 16 <tr> 17 <td>Without enough padding, text feels tight.</td> 18 <td>With padding, text is readable.</td> 19 </tr> 20</table> 21 22</body> 23</html>
In this example, the table cellpadding value is set to 10 pixels, which increases the gap between the text and the cell edge. This makes the content easier to read.
Cell spacing changes the distance between two cells in a table. You can set this either through the HTML attribute or by using the CSS border-spacing property.
Example with HTML attribute:
1<!DOCTYPE html> 2<html> 3<head> 4<title>Cellspacing Example</title> 5</head> 6<body> 7 8<table border="1" cellspacing="10"> 9 <tr> 10 <td>Cell One</td> 11 <td>Cell Two</td> 12 </tr> 13</table> 14 15</body> 16</html>
Here, the cellspacing specifies a gap of 10 pixels between single cells. If your design needs clear separation between adjacent cells, spacing can make a big difference.
The difference between cellpadding and cellspacing is easier to understand if you compare them directly.
| Feature | Cellpadding | Cellspacing |
|---|---|---|
| Purpose | Adds padding inside the table cell between text and cell edge | Adds space between adjacent cells |
| Controlled by | cellpadding attribute or css padding property | cellspacing attribute or border spacing |
| CSS Alternative | padding inside td | border-spacing in table |
Modern HTML practices prefer CSS over attributes like cellpadding and cellspacing. CSS offers more flexibility, making it easier to create consistent table styles across a website.
1<style> 2table { 3 border-collapse: separate; 4 border-spacing: 15px; /* table cellspacing value */ 5} 6 7td { 8 padding: 8px; /* cellpadding property alternative */ 9} 10</style>
In this example, border-spacing is used to control the table's cellspacing value, and padding is used for the space inside each table cell.
When you set border-collapse: collapse, cell spacing is removed. The borders of adjacent cells merge into one. This means you can still adjust the padding inside cells, but there will be no space between them. If your design depends on visual separation between cells, consider using border-collapse: separate instead.
Sometimes, a table may need different amounts of padding and spacing at the same time. This can help with visual hierarchy or highlight certain sections.
1<style> 2table { 3 border-spacing: 20px 5px; /* Horizontal and vertical spacing */ 4} 5td { 6 padding: 12px; /* table cellpadding value */ 7} 8</style>
By setting different horizontal and vertical values for border-spacing, you can control the look more precisely. This is useful for HTML tables that have both text and images.
This diagram shows the relationship between a table element, cell spacing, and cell padding. On one side, cell spacing is the space between the borders of two single cells. On the other side, cell padding is the padding inside each table cell.
In older HTML versions, the cellspacing attribute was common. But in modern doctype HTML mode, it’s better to use CSS for spacing. In quirks mode, cellspacing can behave differently across browsers, which may lead to inconsistent layouts.
The CSS padding property offers more flexibility than the old cellpadding attribute. You can control padding for each side separately.
1css 2td { padding: 15px 5px; }
This gives 15 pixels of padding vertically and 5 pixels horizontally. Using this method, you can fine-tune the spacing for each table cell.
Sometimes, the cellpadding value table directly affects the readability of a layout in web pages. If the text inside cells is too close to the cell edge, users might find it hard to follow. Adjusting the cellpadding value of the table can make a noticeable improvement in user experience, especially for data-heavy HTML tables.
The border spacing property can take one or two values. When you give it one value, it applies equally to both horizontal and vertical spacing. When you give it two values, the first applies horizontally and the second vertically.
1table { border-spacing: 20px 10px; /* specifies the space horizontally and vertically */ }
This is a modern way to control the table cellspacing value without relying on the cellspacing attribute.
When using the table tag, remember that both cellpadding and cellspacing are optional. For some layouts, you might even want no spacing at all, especially if you’re trying to create a grid-like design. But for tables that hold content like text, images, or buttons, leaving at least a small amount of padding inside each cell makes the design look more polished.
Here’s an example where both cellpadding and cellspacing are set through CSS.
1<style> 2table { 3 border-collapse: separate; 4 border-spacing: 12px; /* table cellspacing value */ 5} 6td { 7 padding: 10px; /* padding inside */ 8 border: 1px solid #000; 9} 10</style> 11 12<table> 13 <tr> 14 <td>Item 1</td> 15 <td>Item 2</td> 16 </tr> 17 <tr> 18 <td>Item 3</td> 19 <td>Item 4</td> 20 </tr> 21</table>
This creates a balanced design with both internal cell padding and external spacing between adjacent cells.

The right use of cell spacing and cell padding can make a table easier to read and more professional in appearance. Whether you prefer HTML attributes like cellpadding and cellspacing or modern CSS methods like border-spacing and padding, the goal is to create a balanced layout. By controlling space inside and between table cells, you give your content structure and clarity.
