Remarks
The TableItemStyle class represents the style properties for an element of a control that renders as a TableRow or TableCell. You can control the vertical and horizontal alignment of the contents in an item of the table by setting the HorizontalAlign and VerticalAlign properties, respectively. You can also specify whether the contents of the cell automatically continue on the next line when the end of the cell is reached by setting the Wrap property.
This class provides methods that are useful for creating a style for an item in the Table control. You can use the CopyFrom and MergeWith methods to copy or merge the style properties of another TableItemStyle with the instance of the TableItemStyle that the method is called from.
Constructors

Adds information about horizontal alignment, vertical alignment, and wrap to the list of attributes to render. |
| AddAttributesToRender(HtmlTextWriter) |
Adds HTML attributes and styles that need to be rendered to the specified HtmlTextWriter. This method is primarily used by control developers. (Inherited from Style) |

| Reset() |
Removes any defined style elements from the style. |
| SaveViewState() |
A protected method. Saves any state that has been modified after the TrackViewState() method was invoked. (Inherited from Style) |
