Usuually the TOC is created in the source program, like Word or InDesign, and included when it's exported to PDF. Acrobat is not a "content creation" tool.
Do you mean Acrobat Bookmarks that mimic a TOC and appear in a separate pane on the left side of a PDF?
And what version of Acrobat are you using? Reader, Standard, or Pro? Version number?
