This example demonstrates how to format a cell, a range of cells, an entire row or an entire column by applying a style.

1. Access the Style object that specifies the style to be applied to a cell or a range of cells. This style should be added to the Workbook.Styles collection.
2. Assign the required style object to the CellRange.Style property of the cell, cell range, row or column object.

// Access the built-in "Good" MS Excel style from the Styles collection of the workbook.
Style styleGood = workbook.Styles[BuiltInStyleId.Good];

// Apply the "Good" style to a range of cells.
worksheet.Range["A1:C4"].Style = styleGood;

// Access a custom style that has been previously created in the loaded document by its name.
Style customStyle = workbook.Styles["My Good Style"];

// Apply the custom style to the cell.
worksheet.Cells["D6"].Style = customStyle;

// Apply the "Good" style to the eighth row.
worksheet.Rows[7].Style = styleGood;

// Apply the custom style to the "H" column.
worksheet.Columns["H"].Style = customStyle;
