i am adding c# code to the page load event to check for this and run the dynamic logic. the connection string is held in the web.config as is typically seen…

It’s better to mark the table with a css class:

<style type="text/css">
 .releasedata{background:red}
 .testdata{background:yellow}
</style>
<table class='<%= GetTableClassForEnvironment() %>'>...</table>

In your code behind you’d want to add the method

protected string GetTableClassForEnvironment()
{
/*
  parse environment string from web.config using ConfigurationManager.ConnectionStrings 
http://msdn.microsoft.com/en-us/library/system.configuration.configurationmanager.connectionstrings.aspx
*/
}

This wasn’t in your post, but I’m guessing you want to have the table show up in different colors depending on the environment (ie. debug/release/qa). You should look into using web.config transormations. If you do that you can use conditional compilation statements in your code behind and you won’t have to rely on web.config parsing. So your method becomes

protected string GetTableClassForEnvironment()
{
#IF DEBUG
 return "releasedata"
#ELSE
 return "testdata"
#END IF

}
