Can you tell briefly what booktap is as well?
"booktabs is to enable the easy production of tables such as should appear in published scientific books and journals. What distinguishes these from plain LaTeX tables is the default use of additional space above and below rules, and rules of varying `thickness'."
more here:

(note i haven't disabled vertical lines, which i should i guess since the booktabs package argues explicitly against them and messes them up in the output...)
we have often used
void LyXTabular::bookTabs(bool onoff) { use_booktabs = onoff; }
bool LyXTabular::bookTabs() const { return use_booktabs; }
naming for this.
doesn't seem to be the rule in tabular.[Ch]
(just copied it from there)
but if you prefer...
