DataTable represents one table of in-memory data. It contains rows and columns. You can also check out this article, if you want to create a datatable at runtime.

Suppose you want to delete a column from a datatable, they you can delete by using the column name or the column index.

dt.Columns.Remove("Name"); // Here it will remove the Name column from the datatable.


dt.Columns.Remove(2); // Here it will delete the 3rd column from the datatable, because index starts from 0.

Here dt is the object name of my datatable.
