how can I save a Numbers spreadsheet without the formulas

If I'm reading you correctly, you want to Save a document containing only the results currently displayed in one specific column of a table in that document.

If you no longer need a copy of that document containing the formulas, do this:

• Select the column containing the results you need. Copy.
• Go to the Edit menu and choose Paste Formula Results.
• Select and delete the other columns in the table.

If you plan to do the same or similar calculations in future, START with this step:

• Save a copy of the Numbers document for future use.
• then follow the three steps listed above.
