Working with notes in an Excel spreadsheet

With the help of notes, you can add comments to the contents of cells in Excel tables to make the table more informative, and, at the same time, more compact. Most often, such a need arises when you do not want to load the main table with secondary data, which, nevertheless, can be useful. Or the need for notes appears when you need to add important information, but there is no way to change the structure of the table (add a column or row) to enter the necessary data.
