The data grid will not automatically create columns for you when  
pFirstLineContainsHeaders is true. You must first create the columns  
yourself by setting the "columns" property. This keeps columns from  
being created in your UI when importing data.

When pFirstLineContainsHeaders is false then the data grid will try to  
create enough columns to display at least the first row of your data.  
I realize this is inconsistent but the "false" behavior was done in  
the interest of allowing someone to get some data into the data grid  
and displayed relatively quickly using the Property Inspector.
