HTMLTableElement: cellPadding property
Deprecated
Avoid using this feature in new projects.
Some table styling attributes have no effect. They are superseded by CSS.
This feature may be a candidate for removal from web standards or browsers.
The HTMLTableElement.cellPadding property represents the
padding around the individual cells of the table.
A string representing pixels (e.g., "10") or a percentage value (e.g., "10%").
When set to the null value, that null value is converted to the empty string (""), so elt.cellPadding = null is equivalent to elt.cellPadding = "".
js
// Set cell padding to 10 pixels
let t = document.getElementById("TableA");
t.cellPadding = "10";
