Easy. Just invert BitSet.

    InvertedBitset = w.bitset.Invert()

May be method have other name, I not remember exactly.

Although not so easy :)
Inverted bitset will contains also bits of DELETED records.
So we need yet do

        InvertedBitSet.Intersection( tbl.AllRecords() )

I.e. Choose only true valid records.
