footnotes at end of a longtable

[Rolf von Kuhlmann]

Hi,

I want footnotes in a longtable, but they should appear at the end of the table, not 
at the
bottom of the respective pages. This seems not to be covered by any of the examples in
TableExamples.lyx .
Is it possible, or does anybody know a workaround?

Thanks,
Rolf
