Open xml speadsheet border & bold problems

I have been trying to work with Open XML in making a speadsheet.  I have attached the code that puts the data in the spreadsheet.  I let the productivity tool create the header and put it in a class.  I execute the class then open the speadsheet and then edit it..

I need a border around the data cells.  I get them for the strings, but everything is bold.  I need to do this without everything being bold.  The Charges field, the 11 column needs to handled differently with a deciamal in it.  I do not get the border around these cells.

Can anyone help or suggest somewhere to go?

I hope this is understandable.


Thanks,
