At its simplest, a VTable is an array of pointers to functions. VTables are sometimes referred to as VFTables (or Virtual Function Tables) or VMTs (Virtual Method Tables). Any class/struct object with virtual methods contains an internal pointer to a VTable. The VTable layout is implementation dependent, and may frequently contain type metadata (to support DynamicCast) and correction factors needed to support MultipleInheritance.
GTA 4's resource data files often contain structures that are a direct memory dump of a complete class/structure in memory. These classes are sometimes virtual classes and often contain a VTable pointer in them. When the data is loaded into memory, the data is relocated and VTable pointer is corrected to the proper one by the game. It is important to note that the VTable pointer value will change depending on the exact build/version of the resource compiler used. They are a helpful indicator to identify data structures in files. However, that's all they are -- indicators.
Documentation
The following VTable pointer are valid for files generated by the GTA 4 resource compilers:
