The Memory Manager Table contains the whole list of Memory Managers as returned by ManagementFactory.getMemoryManagerMXBeans(). When a MemoryManagerMXBean object is an instance of GarbageCollectorMXBean, then additional information specific to the GarbageCollectorMXBean class will be found in the jvmGCTable, at the same index. Relationships between MemoryManagers and MemoryPools are shown by the Memory Manager-Pool Relation table (jvmMemMgrPoolRelTable).
