default value of a column added to a datatable

Is there a way to set a default value to a column added to a datatable?

Here is where I add the column:

 dsdata.Tables(0).Columns.Add("QCompID13_1", GetType(Integer))

This is in a dataset of 500 records.  I want to set this value to 997 for this column throughout the whole dataset.  Do I have to loop through the whole thing to set the value, or can I just set the value when I create the column?
