C# DataTable Usage Summary

1. Create a new table

 private DataTable vsDt =new DataTable();

2. Clear the contents of the table (the columns in the table are still there)

vsDt.Clear();

3. Clear the columns of the table

vsDt.Columns.Clear();

4. Add columns to the table

vsDt.Columns.Add("BH", typeof(string));
vsDt.Columns.Add("RQ", typeof(string));

5. Add empty rows to the table

 DataRow vsDr = vsDt.NewRow();

If you have gone before adding a blank row N columns have been added to the table, so the newly added empty rows will also have these columns.
6. Add rows to the table

vsDt.Rows.Add(vsDr);
