Changing The Input Cell Of One-Way Data Table

After it's stated Input Cell of One-Way Data Table on What If Analysis and saved the file how can we change the input cell?

In the resulting table select the table all formulas are =TABLE(...). Delete - and go through the What If - Data Table again.

(I copy-pasted the data from somewhere.) When I click the table in the formula line the formula won't show up.

see the attachment for how to create data table

Understood. Thank you very much.
