I am very new to the latex community (1 week) and writing my thesis with latex.

I am trying to built a table using the following code:

begin{center}

begin{longtable} [c] { |m{3cm}|m{2cm}|m{2cm}|m{2cm}|m{2cm}|m{2cm}|}

        caption{Rating scale for total growth area label{GrowTable}}

            hline 

            centering Total Growth Area (m$^2$) & centering 100 or less & centering 100-115 & centering 115-130 & centering 130-145 & centering 145 or more

            hline

            centering Rating & centering cellcolor{red} 1 & centering cellcolor{red} 2 & centering cellcolor{yellow} 3 & centering cellcolor{green} 4 & centering cellcolor{green} 5 

            hline

end{longtable}

end{center}

It gives me the exact table I want but also provides errors which I do not know how to omit:

1. Extra alignment tab has been changed to cr. centering


2. Extra alignment tab has been changed to cr. end


3. Misplaced noalign. hline


4. Misplaced omit. centering


5. Misplaced omit. end

Current version of table that I want and is the output but with errors:

Based on the information you've provided so far, here is how I would structure the table:

• I'd use a tabularx environment, set its width to textwidth, and let LaTeX calculate the widths of the five data columns.




• While it looks like a good idea to center the contents of the five data cplumns, the material in the left-most column probably looks better if it's typeset ragged-right (aka flushleft).




• Use en-dashes to "connect" numbers, i.e., write 100--115 rather than 100-115, etc.




• Set the parameter extrarowheight to a small positive length, e.g., 2pt, in order to give the table a more open "look". While on the subject of giving the table a more open and inviting "look", do please get rid of all vertical lines. They're simply not needed, unless one is a big fan of the "prison cell" look...

Thank you Mico, Leandriis and David Carlisle!!! You are awesome!!!!!

I didn't have user package array but now I do and I defined a new column! :-D

begin{table} 

    centering

    caption{Rating scale for total growth area label{GrowTable}}

    begin{tabular}{| M{2cm} | M{2cm} | M{2cm} | M{2cm} | M{2cm} | M{2cm} |}

    hline 

        Total Growth Area (m$^2$) & 100 or less & 100-115 &  115-130 & 130-145 & 145 or more \

    hline

        Rating & cellcolor{red} 1 & cellcolor{red} 2 & cellcolor{yellow} 3 &  cellcolor{green} 4 & cellcolor{green} 5 \

    hline

    end{tabular}

end{table}

Worked!!!! :-)
