Problem with condition in a table by using counters
I'm trying to make a conditional dynamic table that uses counter for comparison but i got a irrational error, Please see the following code:
% !TEX TS-program = xelatex
documentclass[hidelinks]{article}
usepackage{pgffor}
usepackage{longtable}
newcounter{generalCounter}
begin{document}
defanyy{a}
begin{longtable}{cccc}
setcounter{generalCounter}{0}foreachelement inanyy{stepcounter{generalCounter}}
ifnumthegeneralCounter=1
1 & 2 & 3 & 4 \hline
fi
ifnumthegeneralCounter=2
1 & 2 & 3 & 4 \hline
fi
end{longtable}
end{document}
This code works fine, but if i change defanyy{a} to defanyy{a,b}, can not build and showen error is ! Incomplete ifnum; all text was ignored after line 11.

The looping with foreach isn't the issue, but anyy isn't getting expanded correctly. In addition, the test ifnum begins in one tabular cell and ends in other ones -- this is weird and can be catched only with tricks.
A simpler way is to use prg_replicate:nn here, a, expl3 macro, that performs expandable loops and survives the grouping involved with tabular cells.
The helper macro generatelines stores the argument in a clist and counts its elements with clist_count:N, which is the number of repetitions to be made.
The actual tabular line entry is another, 'freely' configurable helper macro, e.g. modeltableentry.
documentclass{article}
usepackage{longtable}
usepackage{xparse}
newcommand{modeltableentry}{%
1 & 2 & 3 & 4 tabularnewline hline
}
ExplSyntaxOn
NewDocumentCommand{generatelines}{+m}{%
clist_set:Nx l_tmpa_clist {#1}
prg_replicate:nn {clist_count:N l_tmpa_clist } {modeltableentry}
}
ExplSyntaxOff
begin{document}
newcommand{anyy}{a,b}
begin{longtable}{cccc}
generatelines{anyy}
end{longtable}
renewcommand{anyy}{a,b,c,d,e,f,g,h,i,j,k}
begin{longtable}{cccc}
generatelines{anyy}
end{longtable}
end{document}
