To be clear, this isn't about data that isMissing[], but ratherImport[XXXX,{"HTML", "Data"}]giving "tables" that have rows with inconsistent lengths.

You can solve this by importing "FullData" rather than "Data".
dataA1 = Import[
"http://www.nuforc.org/webreports/ndxe201804.html", {"HTML",
"FullData"}]
dataA2 = Flatten[Most@Rest@dataA1[[8]], 1]
dataA3 = Map[AssociationThread[dataA1[[8, 1, 1]], #] &, dataA2];
Dataset[dataA3]
What's awkward about this is that there can be many empty tables that you must sift through (as you can see, I have to get the 8th element). However, it works quite well in this case.
$endgroup$
$begingroup$
Thank you, but I'm not completely sure how "Data" and "FullData" differ. Why do they exist separately?
