# How to: Manipulate a Table's Row Groups through the RowGroups Property
This example demonstrates some of the more common operations that can be performed on a table's row groups through the <xref:System.Windows.Documents.Table.RowGroups%2A> property.  
  
## Example  
 The following example creates a new table and then uses the <xref:System.Windows.Documents.TableRowGroupCollection.Add%2A> method to add columns to the table's <xref:System.Windows.Documents.Table.RowGroups%2A> collection.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_Add](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_add)]
 [!code-vb[TableSnippets2#_Table_RowGroups_Add](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_add)]  
  
## Example  
 The following example inserts a new <xref:System.Windows.Documents.TableRowGroup>.  The new column is inserted at index position 0, making it the new first row group in the table.  
  
> [!NOTE]
> The <xref:System.Windows.Documents.TableRowGroupCollection> collection uses standard zero-based indexing.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_Insert](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_insert)]
 [!code-vb[TableSnippets2#_Table_RowGroups_Insert](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_insert)]  
  
## Example  
 The following example adds several rows to a particular <xref:System.Windows.Documents.TableRowGroup> (specified by index) in the table.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_AddRows](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_addrows)]
 [!code-vb[TableSnippets2#_Table_RowGroups_AddRows](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_addrows)]  
  
## Example  
 The following example accesses some arbitrary properties on rows in the first row group in the table.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_ManipRows](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_maniprows)]
 [!code-vb[TableSnippets2#_Table_RowGroups_ManipRows](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_maniprows)]  
  
## Example  
 The following example adds several cells to a particular <xref:System.Windows.Documents.TableRow> (specified by index) in the table.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_AddCells](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_addcells)]
 [!code-vb[TableSnippets2#_Table_RowGroups_AddCells](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_addcells)]  
  
## Example  
 The following example access some arbitrary methods and properties on cells in the first row in the first row group.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_ManipCells](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_manipcells)]
 [!code-vb[TableSnippets2#_Table_RowGroups_ManipCells](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_manipcells)]  
  
## Example  
 The following example returns the number of <xref:System.Windows.Documents.TableRowGroup> elements hosted by the table.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_Count](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_count)]
 [!code-vb[TableSnippets2#_Table_RowGroups_Count](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_count)]  
  
## Example  
 The following example removes a particular row group by reference.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_DelRef](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_delref)]
 [!code-vb[TableSnippets2#_Table_RowGroups_DelRef](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_delref)]  
  
## Example  
 The following example removes a particular row group by index.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_DelIndex](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_delindex)]
 [!code-vb[TableSnippets2#_Table_RowGroups_DelIndex](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_delindex)]  
  
## Example  
 The following example removes all row groups from the table's row groups collection.  
  
 [!code-csharp[TableSnippets2#_Table_RowGroups_Clear](~/samples/snippets/csharp/VS_Snippets_Wpf/TableSnippets2/CSharp/Window1.xaml.cs#_table_rowgroups_clear)]
 [!code-vb[TableSnippets2#_Table_RowGroups_Clear](~/samples/snippets/visualbasic/VS_Snippets_Wpf/TableSnippets2/visualbasic/window1.xaml.vb#_table_rowgroups_clear)]
