Automatic td adding in HTML?

[pureGold]

So I am creating a table in HTML and CSS, more specifically HTML, and when I put in the data in the td's, it automatically adds a new td to the end of the row. Why is this and how can I stop it?

Example of Code:

<td>9:00</td>    <td class = "CS164" rowspan = "4">CS 164 <p><i>Introduction to Computer Science</i></p> <p>Randell Hall 121</p></td> <!-- Monday-->	<!-- Spans from 9 to 11 -->    <td class = "CI101" rowspan = "3">CI 101 <p><i>Computing and Information Design</i></p> <p>Curtis Hall 341</p></td> <!-- Tuesday -->	<!-- Spans from 9 to 10 -->    <td> </td> <!-- Wednesday -->    <td> </td> <!-- Thursday -->	<td> </td> <!-- Friday -->  </tr>

Not entirely sure what you're saying, is it "</td>" that gets automatically added, because if so then that is correct, you need to have a closing tag

My bad, updated post with code and image. It's not the closing tag of td, on the actual table, it creates a new space.

When you're rowspaning, cell is not merging with the cell beneath it, instead it takes space of it and you just need to skip one cell that space is taken by the cell that you expanding by rowspan.

 

So when you rowspan you need to skip one cell beneath, if you colspan, you need to skip one to the right. but in your case it is only rowspan, but you need to skip cells in more than one row beneath. 

 

Here is example: http://jsfiddle.net/qwLvx612/ you can see yellow cell that is about to get expanded by 2, using rowspan="3". It will push out purple cells beneath, so you need to get rid of them, I did it by commenting them out.

Ah, that makes a lot of sense. Thank you!
