If some row numbers are missing, you will know they are hidden. So for example if you see rows 13, 14, 17, 18, 22, 23 you would know that rows 15, 16, 19, 20 and 21 are missing. There will also be a slightly heavier border between the visible row headings wher rows are missing. In the example above that would be between the 14 and the 17 and between the 18 and the 22.
Select the rows around the missing ones. Then go to the Format menu, pick Rows and then Unhide. With the rows selected you can also press and hold both the Ctrl and Shift keys and press the 9 key on the main keyboard.
On an Airbus A321, the seat numbers near the wings typically include rows around 11 to 14, depending on the specific configuration of the aircraft. These rows are situated just forward and aft of the wing, providing a good view of the wing and engine. For precise seat numbers, it's best to consult the specific seating chart for the Monarch Airlines A321 configuration you are flying on.
Look at the row numbers to the left of the screen. If there are gaps in the number sequence (e.g. 1 2 3 7 8 9), the numbers that are not displayed represent hidden rows. In this example, rows 4, 5, and 6 are hidden.
It depends on what is missing. It might be a case of inserting a few blank rows or columns to enter the data in. You can do that by putting the cursor where you want the extra rows or columns to be and go to the Insert menu and pick Rows or pick Columns. You can then enter the data that is missing and redo the formulas. Whatever is missing, all you can do is enter it and fix up the spreadsheet. If you know what is missing and where you want to put it, then it is not a major problem. Before doing it, save a copy of the file as it is, with a different name, in case you need to go back to it and start again.
