# Extra alignment tab error, on Table

I am trying to make a table in LaTeX. However, I get several extra alignment tab errors and I do not know why.

I have searched here for similar problems but I only found extra alignment tab error and that is a different problem cause by the %, which I do not use. So, I am quite lost, at the moment.

Here is some minimal code that reproduces the error:

\documentclass[a4paper,10pt]{article}

\usepackage[table]{xcolor}
\usepackage[utf8]{inputenc}
\usepackage{tabularx}
\usepackage{array}

%define some nice colors
\definecolor{middleware_green}{RGB}{82, 119, 17}
\definecolor{middleware_white}{RGB}{255, 255, 255}
\definecolor{middleware_light_gray}{RGB}{239, 239, 239}
\definecolor{middleware_dark_gray}{RGB}{153, 153, 153}

%renewing commands for tabularx
\renewcommand{\tabularxcolumn}[1]{>{\small}m{#1}}

%new column type for test tables
\newcolumntype{L}{>{\leavevmode\ignorespaces\raggedleft\arraybackslash\sffamily}X}%
\newcolumntype{C}{>{\leavevmode\ignorespaces\centering\arraybackslash\sffamily}X}%

\newcolumntype{R}{|>{\leavevmode\ignorespaces\color{magenta!70!black}\raggedright\sffamily\bfseries\footnotesize}p{2.5cm}}%

\newcolumntype{W}{|>{\leavevmode\ignorespaces\color{blue!30!black}\centering\arraybackslash\sffamily\footnotesize}X|}%

What am I missing?

• Column types L and C are not defined and there is also a missing & after the second last \multicolumn{1}{|C|}{...}. – Heiko Oberdiek May 15 '14 at 12:45
• Ok, I updated the document, but I still cant get rid of the problem ! – Flame_Phoenix May 15 '14 at 14:32
• Now you have defined five columns for your table, but as @dcmst said, the row starting with Definition & has six columns, as do the next two rows. Edit: Remember that & separates columns, so if there are five & in a row, that means there are six columns. – Torbjørn T. May 15 '14 at 15:11

The tabular content is divided into six columns, but only five are declared with the macro.
\begin{tabular}{|L|L|L|L|L|}         %five columns
