First of all, the expansion of the three-line table is to make a continuation table, which should have the header of the original table.
Move the cursor to the first word in the first row of the spreadsheet, and then press Ctrl+shift+enter.
These three keys should be pressed together.
Then at the top of the spread table, a blank line will appear, and you can type on it at this time, such as "Continued Table 4- 1".
Then copy the title above the spreadsheet.
