Remarks
Use this method to create a System.Collections.IEnumerator-implemented object that can be iterated through to retrieve the contents of each item in the HtmlTableCellCollection collection.
Use the IEnumerator.Current property to get the item currently pointed to in the collection.
Use the IEnumerator.MoveNext method to move to the next item in the collection.
Use the IEnumerator.Reset method to move the enumerator to the initial position.
Note
The IEnumerator.MoveNext method must be called after creating the System.Collections.IEnumerator-implemented object, or after using the IEnumerator.Reset method to move the enumerator to the first item in the collection. Otherwise, the item represented by the IEnumerator.Current property is undefined.
