Graphics, Figures & Tables ⇒ Basic Table fails

[algebraicTopology]

I am just trying to build an incredibly simple table and used this code:

Code: Select all

\begin{table}
    \begin{tabular}{|l|l|l|l|l|l|}
    \hline	
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    1 & 1 & 1 & 1 & 1 & 1 \\ \hline
    \hline
  \end{tabular}
\end{table}

However, when I build with those first and last \hline, it gives errors, doesn't put in the line, and in the top let box writes "height1". If I take out the top and bottom \hline it builds fine, but of course I don't get my desired horizontal lines. I am stumped and feel this is the simplest thing ever I am not seeing.

No problem here.

Code: Select all

\documentclass{article}

\begin{document}
  \begin{table}
    \begin{tabular}{|l|l|l|l|l|l|}
      \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      1 & 1 & 1 & 1 & 1 & 1 \\ \hline
      \hline
    \end{tabular}
  \end{table}
\end{document}

So please prepare a self-contained and minimal example that clearly reproduces the error to give an adequate problem description. And the exact error message(s) from the log file (*.log) could also be helpful.
