Export Project File to Microsoft Access Database

[hl]

When I export a Project File to a Text File, the "bar
style/format" information of the gant chart is not being
exported.

When I export Project File to a Microsoft Access Database,
the "bar style/format" information of the gant chart is
exported. I know this to be true because when I do the
REVERSE (import the access database into Microsoft
Project), I see my formatting intact.

My question is: which table/fields contain the gant chart
bar style/formatting information?
