Adding values to specific DataTable cells

Question

I'm wondering if it's possible to add values to specific DataTable cells?

Suppose I have an existing dataTable and I add a new column, how would I go about adding to the new column's rows without overwriting the existing columns' rows?

As far as I'm aware, there isn't a method for adding to specific cells (unless I'm wrong).

  dt.Rows.Add(a, b, c, d) 

where a, b, c and d are string values. So what if I just want to add to the d column?

Any help would be appreciated.

If it were a completely new row that you wanted to only set one value, you would need to add the whole row and then set the individual value:

DataRow dr = dt.NewRow(); dr[3].Value = "Some Value"; dt.Rows.Add(dr); 

Otherwise, you can find the existing row and set the cell value

DataRow dr = dt.Rows[theRowNumber]; dr[3] = "New Value";
