鱼叉箭的末端/开头处有破折号

Question

我需要插入一支带有破折号的鱼叉箭，它可以位于箭的开头或结尾。

我发现此方法但它只允许我插入普通箭头。

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows}

\makeatletter
\newcommand\@erelb@r[1]{%
  \mathrel{\tikz[baseline=-.5ex]\draw[#1] (0,0)--(0.3,0);}
}
% 0 is for nothing
% 1 is for arrowhead
% 2 is for bar
% 3 is for both
\newcommand{\erelbar}[1]{\@erelbar#1}
\def\@erelbar#1#2{%
  \ifcase\numexpr#1*4+#2\relax
    \@erelb@r{-}\or     % 00
    \@erelb@r{->}\or    % 01
    \@erelb@r{-|}\or    % 02
    \@erelb@r{->|}\or   % 03
    \@erelb@r{<-}\or    % 10
    \@erelb@r{<->}\or   % 11
    \@erelb@r{<-|}\or   % 12
    \@erelb@r{<->}\or   % 13
    \@erelb@r{|-}\or    % 20
    \@erelb@r{|->}\or   % 21
    \@erelb@r{|-|}\or   % 22
    \@erelb@r{|<->|}\or % 23
    \@erelb@r{|<-}\or   % 30
    \@erelb@r{|<->}\or  % 31
    \@erelb@r{|<-|}\or  % 32
    \@erelb@r{|<->|}    % 33
  \else
    \@wrong
  \fi
}
\makeatother
\begin{document}

$a\erelbar{11}b$

$\begin{array}{cccc}
\erelbar{00} & \erelbar{10} & \erelbar{20} & \erelbar{30} \\
\erelbar{01} & \erelbar{11} & \erelbar{21} & \erelbar{31} \\
\erelbar{02} & \erelbar{12} & \erelbar{22} & \erelbar{32} \\
\erelbar{03} & \erelbar{13} & \erelbar{23} & \erelbar{33} \\
\end{array}$
\end{document}

我试过用

\@erelb@r{|\righthaproonup}    % 33

但输出只是这样的：-

将代码改为

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{arrows.meta}

\makeatletter
\newcommand\@erelb@r[1]{%
  \mathrel{\tikz[baseline=-.5ex,>={Classical TikZ Rightarrow[harpoon]}]\draw[#1] (0,0)--(0.3,0);}
}
% 0 is for nothing
% 1 is for arrowhead
% 2 is for bar
% 3 is for both
\newcommand{\erelbar}[1]{\@erelbar#1}
\def\@erelbar#1#2{%
  \ifcase\numexpr#1*4+#2\relax
    \@erelb@r{-}\or     % 00
    \@erelb@r{->}\or    % 01
    \@erelb@r{-|}\or    % 02
    \@erelb@r{->|}\or   % 03
    \@erelb@r{<-}\or    % 10
    \@erelb@r{<->}\or   % 11
    \@erelb@r{<-|}\or   % 12
