I need a reproducer of a real table actually getting truncated. I don't have
one.
I updated the "PROBLEMS" file a few months ago.

+* I sometimes get errors from PNM utilties when using grohtml.
+ pnmcrop: The image is entirely background; there is nothing to crop.

+This appears to be a spurious warning, and given the same input to the
+same version of groff, it appears with some versions of the PNM tools
+but not others (and the generated image is, in fact, not blank.)
+
+For example, for groff's developers, Netpbm 10.0 (Debian 2:10.0-15.4 on
+amd64) does not produce the warning spuriously, but Netpbm 10.73.43
+(Debian 1:10.73.43-5 on aarch64) does.
+
+A test exhibit follows if someone would like to help the Netpbm
+developers chase down this defect.

+
+Use "groff -t -Thtml" with the foregoing input.
