[Tex/LaTex] LaTeX Error: Illegal character in array arg

tables

I am trying to make a table. Following is the sample of the table. But I got Illegal character in array error. I already searched all related question but did not find any solution. What did I do wrong?

   \begin{table*}[!ht]
    \centering
    \caption{Predictor Name and Data Source}
    \label{data}
    \resizebox{\textwidth}{!}{%
    \begin{tabular}{|l|l|l|1|}
    \hline
    \textbf{Type} & \textbf{Predictor Name} & \textbf{Acronym} & \textbf{Data Source} \\ \hline
    \multirow{9}{*}{Predictor} & Company Id & COMID & Lankabd.com \\ 
    \cline{2-4} 
                               & Lower Price & LOWPRCP & Household Size \\
                               \cline{2-4} 
                               & High Price & HIPRC & Male Literacy  \\
                               \cline{2-4} 
                               & Average Price & AVGPRC & Low Land \\
                               \cline{2-4} 
                               & Weighted Average Price & WTAVGPRC & Low Land \\
                               \cline{2-4} 
                               & Trade Number & TRDNO & Low Land \\
                               \cline{2-4} 
                               & Trade Volume & TRDVOL & Low Land \\
                               \cline{2-4} 
                                & Issued Share & ISSUEDSHARE & Low Land \\
                                \cline{2-4}

                               \hline

    \end{tabular}% 
    } 
    \end{table*}

Best Answer

The better way to obtain a table whose width equals that of the textblock is to use a tabular* environment.

I would also like to suggest that you give your table a more "open" look, by getting rid of all vertical rules and by using fewer, but well-spaced, horizontal rules.
