I'm trying to build a table using tabularx but I'm get the following error:

! Undefined control sequence.
<template> ...centering \arraybackslash \compress 
                                              \ignorespaces

Can anyone explain why I'm getting this?

Here's my code

\documentclass{article}

\usepackage[letterpaper, landscape, margin=1in]{geometry}
\usepackage[default,osf]{sourceserifpro}
\usepackage{booktabs}%For tables
\usepackage{enumitem}%For lists
\usepackage{tabularx}%For tables

\begin{document}

    \compress isn't defined by latex or by any package that comes to mind, what do you want it to do, where did you see it documented? – David Carlisle Jun 20 '19 at 18:43

    Try adding \makeatletter\newcommand*{\compress}{\@minipagetrue}\makeatother to your preamble. This \compress command seems to be a thing here in TeX.SX: https://tex.stackexchange.com/a/442442/134574 https://tex.stackexchange.com/a/489185/134574 https://tex.stackexchange.com/a/114287/134574... – Phelype Oleinik Jun 20 '19 at 18:46

    @PhelypeOleinik searching the site for answers again? It'll never catch on:-) – David Carlisle Jun 20 '19 at 18:47
  • @DavidCarlisle At least you can't say I didn't try ;-) – Phelype Oleinik Jun 20 '19 at 18:48

    It is a command which is used to remove the vertical spacing added to a list in a tabular cell. – Bernard Jun 20 '19 at 18:49
  • @PhelypeOleinik that's it ... super helpful. I'd originally built this code some time back an swiped it from that old document. The reference you denoted did the trick! It was in my old document but not in my new one. My real problem was trying to parse the error log to figure out what exactly was the offending code bit. – agf1997 Jun 20 '19 at 18:50
  • Why not use \setlist[itemize,1]{itemindent=12pt, topsep=0pt, before=\vspace{-\baselineskip}, after=\vspace{-\baselineskip}} to remove the space above and below the listing? – leandriis Jun 20 '19 at 18:50

    @agf1997 If TeX tells you Undefined control sequence, the undefined command is always the one at the end of the first line of error which, in this case, is the \compress, which Bernard just explained. – Phelype Oleinik Jun 20 '19 at 18:52
  • @PhelypeOleinik Thanks. Seems obvious in retrospect. I usually associate Undefined control sequence with a package not being loaded so I was trying to find the missing one. – agf1997 Jun 20 '19 at 18:54
  • @leandriis that certainly seems more direct ... not sure about the pros and cons but I'll experiment with that. – agf1997 Jun 20 '19 at 18:55
