Structured tables (Data tables) or, as we call them, named ranges represent a group of cells that have been given a name and a filter to make it easier to view and work with the data they contain. If these tables start from the first cell in the worksheet, you can set the cell header to appear instead of the worksheet header. To be more precise, instead name of the columns they contain.
Since Excel is often used to create business reports it would be useful to find information in the header or footer of the document that details them more closely. This can be: report name, label, company logo, date … And here you can insert the page number, the total number of pages, or some other information that is relevant to the appearance of the report. These functionalities contribute to the uniformity of the document and give it a more professional look.
