The cellpadding attribute specifies the inner space of cells.
We define the cellpadding for cells by the pixels like 20px,30px ,100px or so on .
In simple words cellpadding increase and decrease the size of all cells.
Let's see with an example.
<!DOCTYPE html>
<html>
<head>
<title>HTML Table </title>
</head>
<body>
<table height="150" width="500" border="1"cellspacing="10px"cellpadding="30px">
