You can use the collection editor of the TableLayoutPanel control, called the Column and Row Styles dialog box, to edit the rows and columns of your controls.
If you want a control to span multiple rows or columns, set the
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 Anchor property. For more information, see Walkthrough: Arranging Controls on Windows Forms Using a TableLayoutPanel.
The dialog boxes and menu commands you see might differ from those described in Help depending on your active settings or edition. To change your settings, choose Import and Export Settings on the Tools menu. For more information, see Customizing Development Settings in Visual Studio.
