Shows how to get the index of a node in a collection.

Document doc = new Document(MyDir + "Tables.docx");

Table table = doc.FirstSection.Body.Tables[0];
NodeCollection allTables = doc.GetChildNodes(NodeType.Table, true);

Assert.AreEqual(0, allTables.IndexOf(table));

Row row = table.Rows[2];

Assert.AreEqual(2, table.IndexOf(row));

Cell cell = row.LastCell;

Assert.AreEqual(4, row.IndexOf(cell));
