Question

the pull - down bars for column shown above are missing the column names. what would you select to show them? my data has headers options add level

Explanation:

The "My data has headers" checkbox in the sort dialog box tells the software that the first row of the data contains column names. Checking this box enables the pull-down bars for columns to display the actual header names instead of generic labels. The other options (Options, Add Level) do not control the display of column names in the sort dialog's pull-down bars.

Answer:

My data has headers
