Ok – i’ve found the table formatting. where do i install the downloadable code from these examples?

You can add styles directly to your table or put it in a diff file.
Use this
<table class=”tableborderbottom”>….

add style to file.css
.tavleborderbottom td {border-bottom:4px solid blue;}

Excuse me but i’m a real noob to this. I don’t seem to have a file.css. Are you saying i can create a file called file.css, add it to my theme folder and it will then be used for my tables?

No, I didn’t had a look at your site-source. Your styleshhet is stored here:

In the example you mentioned they use these styles, if you only use one table in your files you can apply it like this (table, tr=row, th= head(first line), td other fields):

table {
font-size:0.9em;
font-family: Arial, Helvetica, verdana sans-serif;
background-color:#fff;
border-collapse: collapse;
width: 100%;
}
tr {
background-color:#fff;
border-bottom: 1px solid #f0f0f0;
}
th {
border-right: 1px solid #fff;
color:#fff;
text-align:center;
padding:2px;
text-transform:uppercase;
height:25px;
background-color: #a3c159;
font-weight: normal;
}
td {
color:#414141;
padding:5px;
text-align:left;
}

No, I’m still not getting this. I’ve created a text file called tables_min.css and placed it in the directory of my current theme.

If i want to use that style in a post how do i refer to it? My advice was something like placing the following at the top of the post:

<style type=”text/css” media=”all”>
@import “tables_min.css”;
and closing the style tag at the end. That doesn’t work however.

Personally, I’d just add the style to your current theme’s style.css.

Located under wp-content/themes/YourThemeName/style.css

That was what i tried first but i managed to screw it up. Trying again it *almost* works. I’ll experiment.
