Rendell signed the bills after the state Legislature held a flurry of votes on the $27.8 billion budget's primary appropriations bill and a key companion bill, ending a 101-day state budget stalemate.

The companion bill taps more than $1.5 billion from the state's reserves.

Table games are expected to produce $200 million in taxes and fees for the state treasury.
