FixedHeaders (v3.1.6): Any reference to original table?

I have some custom header-level elements that have behavior that I would like to maintain on the fixed header. Does anyone know if the created fixed position table has any reference to the dataTable it originated from? I haven't noticed anything that consistently ties it to the table that created it, so far. Just want to make sure there isn't anything out-of-box that I'm missing before I create my own solution. Thanks in advance!
DataTable version: 1.10.20
