This sample demonstrates the Spreadsheet cell formatting feature by applying different styles to a
                    range of cells.
                
                        Cell formatting allows you to highlight cell data that appears in the Spreadsheet. It can be enabled
                        or disabled using the allowCellFormatting
                         property.
                    
                        In this sample, gridlines are hidden using the showGridLines property and the styles are
                        applied using the style property and 
                            cellFormat
                         method.
