Broken tables. Frozen panes. Split screens. This is not debris from a crime spree. These are names of techniques used to manage documents.
To carry forward the heading of a table that’s flowed on to the next page, apply the word processing command to repeat the table heading.
Similarly, to cement the heading of a spreadsheet row and still be able to read row 100, apply the spreadsheet command to freeze rows.
Moving right along, to view and compare two areas of the same document, use the split screen tool.
And finally, to prevent someone else from messing with your workbook, use protection.
I’m not making up these names.
