Hi Judy,
It appears to me that you just swapped the headings for the Name and Birth columns, but the data is still in the same columns. I suggest swapping the column names back to get back to where you were and save it. Then when you are viewing your space page, you can click on any heading arrow to sort by that column. Click again to reverse the sort order based on that column. Keep in mind that blank or empty cells will sort those rows first (if ascending).
Also the To-Do list is a table. The person profile text box editor has an icon for creating a table (hover over the icons for their names). Tho I'm not sure if the free-space text box editor has the same icons.
Hope this helps!
