What does the border button do when clicked in a spreadsheet?

The border button, when clicked in a spreadsheet, adds visual borders around the selected cells. This feature is useful for improving the visual organization of data, making it easier to read and distinguish between different sections. Borders help to visually separate data sets, highlight important information, and create a more professional appearance for printed documents or presentations. This functionality does not alter the content of the cells, adjust their sizes, or modify the font characteristics, which are the roles of alternative formatting tools and options within spreadsheet software.
