The cellpadding and cellspacing attributes are used to control the spacing within and around table cells in HTML. They can be set using the padding and border-spacing properties in CSS, respectively.
Here’s an example of how you can set the cellpadding and cellspacing of a table using CSS:
table {
border-collapse: separate;
border-spacing: 10px;
padding: 10px;
}
This will set the cellspacing to 10px and the cellpadding to 10px for all table elements on the page.
Note that the border-collapse property must be set to separate in order for the border-spacing property to have an effect.
Keep in mind that the cellpadding and cellspacing attributes are deprecated in HTML5, and you should use CSS to style tables instead.
