Help creating HTML table from dataTable when every nth dataTable row = 1 html table row... C#

Hello, Im trying to create an html table from data that is in a dataTable but Im having trouble coming up with the right logic. Every 3 rows in the dataTable needs to be 1 row in the html table.  Ive tried using foreach through the datatable with a modulus to determin every third dataTable row but i still run into snags because i am building the table using objects rather than using concatenated strings..(example TableRow tr = new TableRow  etc...). I cant add the cells to the rows when the row is only created in an if statement etc. Can someone post a good example in c# of how they would achieve this. The amount of data in the dataTable could change from time to time so the code cant rely on a pre determined size, unless you just need the total rows and columns, that can be dtermined when the dataTable is filled from the sqlDataReader. <table><tr><td>dataTable row 1 values</td><td>ataTable row 2 values</td><td>dataTable row 3 values</td></tr> <tr><td>dataTable row 4 values</td><td>dataTable row 5 values</td><td>dataTable row 6 values</td></tr>   Any help and example would be great. Ive been able to do similar tables in other apps but thats only when I use concatenated text strings to build the html table. Im trying to stay away from that this time

Creating your SharePoint Governance Plan

One of the most common questions that I get from prospects as I'm talking to them about the creation of a governance plan and process is what does it look like.

Creating a Generic Entity Framework 4.0 Repository

With .NET 4.0 right around the corner, I thought it would be cool to download Visual Studio 2010 beta 2 and start playing around with the next release of Entity Framework.

The initial release of Entity Framework came with a great deal of criticism. To make matters worse, there was a large uproar when it was rumored that Microsoft would be abandoning LINQ to SQL, in favor of Entity Framework. This was because, at the time, many developers felt Entity Framework was an inferior technology to LINQ to SQL. To set things right, Microsoft proactively moved forward with improving Entity Framework, in time for the 4.0 release of the .NET Framework. This is good news because my initial impressions, so far, have been nothing but positive.
