There are some problems in the following MWEs. First example looks the same with MkIV and LMTX, second uses \NS that is only in LMTX.
The first column is justified even if it’s defined as left aligned; this happens also with a simple "l" column. With "p" the width is ignored. With \NS the alignment is also wrong in the same way. \starttext \starttabulate[|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|] Default \NC Linux \NC MacOS \NC Windows \NC\NR \HL Text Proc \NC LibreOffice \NC Apple Pages \NC MS Office (Word) \NC\NR PDF Viewer\NC Evince \NC Preview \NC Edge \NC\NR \stoptabulate \starttabulate[|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|lp(.2\textwidth)|] Default \NC Linux \NC MacOS \NC Windows \NC\NR \HL Text processor \NS[3][l] LibreOffice or else \NC\NR Drawing \NS[2][lp(.4\textwidth)] Inkscape \NC Corel Draw \NC\NR Simple Editor \NC Nano \NC TextEdit \NC Notepad \NC\NR \stoptabulate \stoptext Additional question: How would I define those columns to use the whole \textwidth ?
