Difference between <TD> & <TH> Tags (Dreamweaver)

I have a basic website built via dreamweaver with tables. I asked InfoLinks if my site was compatible with their service (I use it on some of my other websites) and after some back & forth emails they told me I need to change the <TH> tags to <TD> tags.

I looked at my code and it looks like I have both <TH> & <TD> Tags.

I looked up the definition of <TD> & <TH> Tags and from what I can gather it looks like <TH> refers to the Table Header and <TD> refers to the Table Data.

Does anyone know if I can just go through and change all the <TH> tags to <TD> tags without running into any problems?

 

You are right TH is for the Table Header,
TD is like a CELL inside a table.

It depends on what you are using your TH tags for, you can change them to TD tags for sure and get them to span accross if this is what the TH were doing.

Of course it's better to not use tables at all for your layout!

 

What do you use for your layout?

 

Mainly DIV's and use of CSS to control the presentation. So a typical layout for a page would be:

<div id="header">Header Goes Here Usually includes a menu and a logo</div>
<div id="content">Main Content Goes Here May contain more than 1 DIV if more than 1 column</div>
<div id="footer">Footer Goes Here</div>

Code (markup):

And to develop that further a simple 1 column page:

<div id="header">
    <img src="logo.jpg" />
    <ul id="menu">
       <li><a href="link1.htm">LINK 1 </a></li>
       <li><a href="link2.htm">LINK 2 </a></li>
       <li><a href="link3.htm">LINK 3 </a></li>
    </ul>
</div>
<div id="content">Main Content Goes Here May contain more than 1 DIV if more than 1 column</div>
<div id="footer">© All Rights Reserved 2009</div>

Code (markup):

Then you can use CSS to refer to individual elements and alter the presentation, meaning backgrounds borders gaps colours hover colours etc.. basically present things how you want.

 

td goes inside th am i right?

 

No,

TH is table header cells, by defult i think the text is centered where in TD it's left. Of course you can use CSS to style the different types of cell.

<table>
<tr><th>Table Header!!</th></tr>
<tr><td>Table Cell</td></tr>
