Remarks

Use this Add method overload to create a new custom style based on existing cell formatting. Format settings are obtained from the top-left cell of the specified cell range. If the source cell has no formatting applied, the Spreadsheet creates a cell style with format settings identical to the Normal built-in style.

Take into account the following rules when you name a new style:

• A style name must be unique. Use the StyleCollection.Contains method to ensure that the collection does not contain a style with the specified name.

• A style name cannot be empty.

The new style has all StyleFlags set to true. To change the style’s format characteristics, modify the Style object’s properties within the Formatting.BeginUpdate - Formatting.EndUpdate method calls.

C#

// Create a style based on format settings of the "B2" cell.

// Modify the style's format characteristics if needed.
