\cvsubentry extra alignment and misplaced \omit fix

[boi-wan]

When using \cvsubentries and \cvsubentry elements, XeLaTex compiler raises the below errors:

1. Extra alignment tab has been changed to \cr.
   [...]
   You have given more \span or & marks than there were
   in the preamble to the \halign or \valign now in progress.
   So I'll assume that you meant to type \cr instead.
   OverLeaf hint:
   You have written too many alignment tabs in a table, causing one of them to be turned into a line break. Make sure you have specified the correct number of columns in your table.

2. Misplaced \omit.
   \multispan ->\omit
   @multispan
   [...]
   I expect to see \omit only after tab marks or the \cr of
   an alignment. Proceed, and I'll ignore this case.

First error seems to be caused by a missing new line command inside the \cvsubentry declaration on awesome-cv.cls.

This piece of code:

\newcommand*{\cvsubentry}[4]{%
\setlength\tabcolsep{0pt}
  \setlength{\extrarowheight}{0pt}
  \begin{tabular*}{\textwidth}{@{\extracolsep{\fill}} L{\textwidth - 4.5cm} R{4.5cm}}
    \setlength\leftskip{0.2cm}
    \subentrytitlestyle{#2} & \ifthenelse{\equal{#1}{}}
      {\subentrydatestyle{#3}}{}
    \ifthenelse{\equal{#1}{}}
      {}
      {\subentrypositionstyle{#1} & \subentrydatestyle{#3} \\}
    \ifthenelse{\equal{#4}{}}
      {}
      {\multicolumn{2}{L{17.0cm}}{\subdescriptionstyle{#4}} \\}
  \end{tabular*}
}

should become:

\newcommand*{\cvsubentry}[4]{%
\setlength\tabcolsep{0pt}
  \setlength{\extrarowheight}{0pt}
  \begin{tabular*}{\textwidth}{@{\extracolsep{\fill}} L{\textwidth - 4.5cm} R{4.5cm}}
    \setlength\leftskip{0.2cm}
    \subentrytitlestyle{#2} & \ifthenelse{\equal{#1}{}}
      {\subentrydatestyle{#3}}{} \\
    \ifthenelse{\equal{#1}{}}
      {}
      {\subentrypositionstyle{#1} & \subentrydatestyle{#3} \\}
    \ifthenelse{\equal{#4}{}}
      {}
      {\multicolumn{2}{L{17.0cm}}{\subdescriptionstyle{#4}} \\}
  \end{tabular*}
}

Second issue, seems to be related to a problem between \ifthenelse and \multicolumn.

As stated here, \multicolumn must be the first thing TeX sees in a table cell, after expanding commands; unfortunately, the workings of \ifthenelse leave something before \multicolumn when the test is computed false.

A good solution could be to use a different test making command.

I ran into a Tex capacity exceeded when trying to use this with xelatex.

! TeX capacity exceeded, sorry [input stack size=5000].
\reserved@a ->\def \reserved@a 
                               *{\@hspacer }\reserved@a 
l.48     }

Small example that triggered the issue for me.

\documentclass[10pt, a4paper]{awesome-cv}
\geometry{left=1.4cm, top=.8cm, right=1.4cm, bottom=1.8cm, footskip=.5cm}
\fontdir[awesome-cv/fonts/]
\colorlet{awesome}{awesome-red}
\setbool{acvSectionColorHighlight}{true}

          }
        \cvsubentry

            \end{cvitems}

    }

I did find another way, it appears tabular* is quite space sensitive and once line 625 in the original is fixed, and switched to using different if statements see #314, adding % to the end of all of the lines fixes the unusual alignment of the entries after the first. See #357 for more info.
