Solution
When importing a table in the latest version of LabVIEW, you can make the top row and first column editable by right-clicking on the table and selecting Editable Headers.

Once you have enabled the Editable Headers, you can make changes and determine the position of the headers while running.
This feature has been added to new versions of LabVIEW; because of that, you could do this on the old version without enabling the feature.
