It takes two arguments, the first cell and the rest.  I would really like to have a simple macro ```\\parrayline``` so that I can write\r\n```LaTeX\r\n\\symdef{matrix}[2}{\\begin{array}{*{#1}}#2\\end{array}}\r\n\\symdef{mrow}[1]{\\varparrayline{#1}}\r\n\\matrix{3}{\\mrow{1,2,3}\\mrow{4,5,6}}\r\n```\r\nthe macro ```matrix``` works well, I have started a macro ```\\varparrayline``` but I still have problems doing the LaTeX macro. But we should have a LaTeXML binding for the time when I have solved the LaTeX problems. Then I want to refactor the ```\\parrayline``` as ```\\varparrayline```. \n\n_Copied from original issue: KWARC/sTeX#13_"}}
