# Persistent error with tabularx

I'm trying to have a table that uses the entire page width in 3 columns and use a bullet point in each item. I came up with the following code

\begin{tabularx}{\textwidth}{Y Y Y}

$\bullet$ Item A & $\bullet$ Item B & $\bullet$ Item C \\
\end{tabularx}


However every time I compile it, I get a series of erros on the same line, as shown in the attached picture.

Here is a minimum example that reproduces the error

\documentclass{article}
\usepackage[brazilian]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tabularx}
\newcolumntype{Y}{>{\left\arraybackslash}X}

\usepackage{geometry}
\geometry{
a4paper,
total={170mm,267mm},
left=20mm,
top=20mm,
}
\begin{document}

\begin{tabularx}{\textwidth}{Y Y Y}

$\bullet$ Item A & $\bullet$ Item B & $\bullet$ Item C \\

\end{tabularx}
\end{document}

• What's the \left doing in the definition of Y? Nov 28 '17 at 17:13
• If you want to have left alignment, then \raggedright is the command to use, not \left, which is a command for math material. Nov 28 '17 at 18:36
\newcolumntype{Y}{>{\raggedright\arraybackslash}X}

The command \left has a completely different meaning.
