No, there's no table of components, but you can find them all in the Graph field of the sys_cb_topic table JSON-formatted.
I suppose if you really wanted, you could export that table and mockup your own dataset using that formatted data, but if you're just looking for something specific, say, all the references to a certain field or text across all topics, you can simply do a query on that Graph field (or a For Text/Keywords search).
Note the sys_cb_topic table will show the latest version of what you see in VA Designer, which can include unpublished topics and topic versions. The Definition field of the sys_cs_topic table is somewhat similar - JSON-formatted also - but is the published version of each topics.
One last note: just in case what you're looking for is even simpler - a clean table-formatted view of nodes within a single topic - use the Table View option within the top menu bar of VA Designer 🙂
