What you are missing, I suspect is that Apple does not consider this an issue.
Numbers tables conform to a data base model in which each row is a record, and each column is a field in the record.
You can delete a record or insert a record by deleting or inserting a row.
You can delete a field from, or add a field to, all records in the table by deleting or adding a column.
That said, you can easily delete the contents of a single cell and move the contents of all cells below it up one row with these steps:
- Select the cell below the one you want to 'delete'.
- Scroll to the bottom of the table, then shift-click on the last cell in that column to add it and all cells between it and the single cell you selected above to the selection.
- Press command-C to copy the contents of these cells to the clipboard.
- *Click any cell not included in the selection to deselect those cells, then click once on the bottom cell of the column containing the cell to be 'deleted,' and press delete to remove the contents of that cell.*
- Scroll back to the cell you wish to 'delete'. Click once on that cell to select it.
- Press command-V to paste the contents copied from the cells below into the 'deleted' cell and those below it.
Done.
*This step is the cautious approach that removes the contents of only the last cell in the column, and, at the step following, replaces the content of each remaining cell with the content copied from the cell below it when you press command-V.
You can omit the starred step by pressing command-X instead of command-C at the step before. This 'cuts' the content from the selected cells and places it on the clipboard. Until you complete the next step (selecting the cell to be 'deleted' and pasting the clipboard content back into the table), the only copy of that data is the copy on the clipboard (plus any backup copies).
Takes many words to describe, but very little action to accomplish.
