With HTML, you can easily add HTML tag inside a table. The tag should open and close inside the <td> tag. For example, adding a paragraph <p>…</> tag or even a list tag i.e. <ul>…<ul>.
Example
You can try to run the following code to use an HTML tag <ul>…</ul> inside HTML table
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td { border: 1px solid black; width: 400px; }
</style>
</head>
<body>
<h1> Total Points</h1>
<table>
<tr>
<th>Technologies</th>
<th>Points</th>

<tr>
