Simple but frustrating HTML table problems

[jesterpunch]

Hello folks,

I taught myself HTML 9 years ago and have been using it extensively ever since, so I feel embarassed to ask for help, although I never feel shy to ask for help with PHP!

My problem is as follows, my tables are going all crazy when I view them on my webspace and I can't figure out why.

Take a look:

http://theunsentletter.com/wdap/Assignment_2/index.php

Clearly the intro to my site isn't meant to be 2cm wide, yet the table code, to me, says it shouldn't.

Please help me!

The first script is the front page, the following scripts are the embedded php files.

<table width="750px" align="left" border="0">
<tr>
<td>
<?php include('title.php');?>
</td>
</tr>
<tr valign="top">
<td width="250px">

<h3>Select your School Colours:</h3>

<form name="styles" action="<?php echo(htmlentities($_SERVER['PHP_SELF'])); ?>" method="post">
<select name="styles">
<option value="standard.css"<?php if($_SESSION['styles'] == "standard.css"){ echo(" selected=\"selected\" "); }?>>Standard</option>
<option value="chs.css"<?php if($_SESSION['styles'] == "chs.css"){ echo(" selected=\"selected\" "); }?>>Cronulla High</option>
<option value="khs.css"<?php if($_SESSION['styles'] == "khs.css"){ echo(" selected=\"selected\" "); }?>>Kirrawee High</option>
</select>
<input type="submit" value="Submit">
</form>

<br>


<?php include('linksColumn.php');?>

<td width="500px" align="left">

Your table is unbalanced, the first row contains just one column, the second row contains two columns. Try
<td colspan="2">
<?php include('title.php');?>
</td>Btw., including complete HTML documents isn't a good idea, your document has three BODY tags, for example.
