How to: Edit Columns and Rows in a TableLayoutPanel Control

You can use the collection editor of the xref:System.Windows.Forms.TableLayoutPanel control, called the Column and Row Styles dialog box, to edit the rows and columns of your controls.

Note

If you want a control to span multiple rows or columns, set the RowSpan and ColumnSpan properties on the control. For more information, see Walkthrough: Arranging Controls on Windows Forms Using a TableLayoutPanel.

If you want to align a control within a cell, or if you want a control to stretch within a cell, use the control's xref:System.Windows.Forms.Control.Anchor%2A property. For more information, see Walkthrough: Arranging Controls on Windows Forms Using a TableLayoutPanel.
