pandoc转换markdown生成pdf文件表格问题
使用pandoc转换Markdown文件(.md)生成pdf
pandoc --latex-engine=xelatex -V CJKmainfont="Noto Sans CJK SC" -s --toc --toc-depth=2 --highlight-style zenburn --template=pandoc-template.tex -o output.pdf input.md
产生错误：
! Undefined control sequence.
l.180 \toprule
原因：由于markdown文件里面有表格，转换成latex时候需要booktabs包生产表格，安装booktabs包应该可以解决问题。
但ubuntu下MikTex Console安装booktabs package失败，提示服务器错误。可使用如下sty文件，加入Miktex搜索路径问题解决。
