DataTable compute function on non standard datatypes

Question

I have a problem with the following situation. Instead of using a standard datatype in my datatable column I have the following XYSet structure.

public struct XYSet
        {
            public int x1;
            public int y1;
            public int x2;
            public int y2;
            public double rc;
            public double offset;
        }

m_resultTable.Columns.Add(new DataColumn("A", typeof(XYSet)));
m_resultTable.Columns.Add(new DataColumn("B", typeof(XYSet)));

Now I would like to use the Compute function of DataTable in order to calculate the standard deviation of the rc values in both A and B XYSet column. Is it possible the use the Compute function or do I have t create a new datatable having all structure values in a their own column after which the Compute function can be used.

Thanks for helping me out.
