Adding xepersian produces an error for tables

Question

Adding \usepackage{xepersian} makes the following code produce an error:

\documentclass{article}

\usepackage{booktabs,caption,dcolumn}

\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{makeidx}

Is there a way to solve this problem?

Answer 1

There is an error in the definition of \newcolumntype with dcolumn, the correct syntax is \newcolumntype{d}[1]{D{.}{.}{#1}}

Using . as separator in the output with xepersian result an error???, you can replace it with \newcolumntype{d}[1]{D{.}{\mbox{.}}{#1}}.

Result

Answer 2

The xepersian package makes . into a math active character, in order to fix the order of digits, I guess.

You can define a “normal” version of the period in math mode by

\DeclareMathSymbol{\decimalperiod}{\mathord}{letters}{"3A}

However, you have also to include the tabular in a latin environment. I also fixed the order of package loading (removing the useless lmodern).

\documentclass{article}

\usepackage{fontspec}
\usepackage{booktabs,caption,dcolumn}
\usepackage{amsmath}
\usepackage{amssymb}

\usepackage{thmtools}
\usepackage{titlesec}
\usepackage{textcomp}
\usepackage[svgnames]{xcolor}
\usepackage[hidelinks]{hyperref}
\usepackage[noabbrev,capitalize]{cleveref}

\usepackage{xepersian} 
\settextfont{Amiri}    

\DeclareMathSymbol{\decimalperiod}{\mathord}{letters}{"3A}

\newcolumntype{d}[1]{D{.}{\decimalperiod}{4}}% column type for figures with 4 decimals
\newcommand{\subhead}[1]{\multicolumn{1}{c}{#1}}% to format sub-headings of d-type columns

With siunitx instead of dcolumn you get a better result, without any issue from .

\usepackage{textcomp}
