"How do I setup tabs for leader symbols (decimals) within a table?

Hi Everyone!

I'm setting up an appendix for attachments to a report labeling each against
a letter of the alphabet using leader periods with tabs to arrange them. But
the letters look all crooked. I'd like to put all the appendices in a table
but when I do the table doesn't recognize the tabs or leader periods I set to
separate the name of the appendix and its assigned corresponding letter.

Help? My questions is "How do I setup tabs for leader symbols (decimals)
within a table?"

Thanks for your time to help me out!
