One of the questions we get more often from Authorea our  users at Authorea  is: \textit{why is my this  LaTeX table command  not working?} The short answer to that question is: \textbf{because that LaTeX command was not intended for a webpage; it was intended for the printer.}     Authorea is a collaborative editor for technical and scholarly documents which understands and renders markup languages such as Markdown, and LaTeX. We do enjoy and use LaTeX frequently at Authorea. This post for example, was written on Authorea in LaTeX. Let's grab a pre-baked equation, for example this Fourier transform: \verb|a \Leftrightarrow 2\pi a\sum\limits_{k = - \infty }^\infty {\delta (\omega + 2\pi k)} ,( - \infty < n < \infty )| and render it as:     \begin{equation}   a \Leftrightarrow 2\pi a\sum\limits_{k = - \infty }^\infty {\delta (\omega + 2\pi k)} ,( - \infty < n < \infty )   \end{equation}     We decided to support LaTeX from the very beginning, as it is the document preparation markup of choice for a large portion of researchers in the hard sciences.
