LaTeX: Rotated header lines in table beginning in the same line

Question

i have a table with rotated text. All these header lines should start near the second \hline (similar to "Abs.") like

hline
   C
  BC
  BCD
1 BCD
l BCD
o BCD Frequency
CABCD Abs   Rel
hline

\begin{table}[htbp]
\begin{tabular}{rrrrrrr}
\hline
\multirow{6}{*}{\rotatebox[origin=cb]{90}{Col1}} & \multirow{6}{*}{\rotatebox[origin=cb]{90}{A}} & \multirow{6}{*}{\rotatebox[origin=cb]{90}{BBBBB}} & \multirow{6}{*}{\rotatebox[origin=cb]{90}{CCCCCC}} & \multirow{6}{*}{\rotatebox[origin=lc]{90}{DDDDD}} & & \\
& & & & & &\\
& & & & & &\\
& & & & & &\\
& & & & & \multicolumn{2}{c}{Frequency} \\
& & & & & Abs. & Rel.\\
\hline
1&9&8&7&6&5&4\\
\end{tabular}
\end{table}

I tried different origin like l, r, cB, cb, ct, ... but it doesn't look like the way i would prefer. what do i wrong? thank you!

No need to use all those \multirows; here's a possible solution:

\documentclass{article}
\usepackage{graphicx}
\usepackage{multirow}

\begin{document}

\begin{table}[htbp]
\begin{tabular}{*{7}{r}}
\hline
& & & & & \multicolumn{2}{c}{\multirow{7}{*}{Frequency}} 
\\
\rotatebox{90}{Col1} & \rotatebox{90}{A} & \rotatebox{90}{BBBBB} 
  & \rotatebox{90}{CCCCCC} & \rotatebox{90}{DDDDD} & Abs. & Rel. \\
\hline
1&9&8&7&6&5&4 \\
\end{tabular}
\end{table}

\end{document}

As a side note, to make your tables look professional, you might be interested in the booktabs package (this implies that your tables won't use vertical rules):

\documentclass{article}
\usepackage{graphicx}
\usepackage{multirow}
\usepackage{booktabs}

\begin{document}

\begin{table}[htbp]
\begin{tabular}{*{7}{r}}
\toprule
& & & & & \multicolumn{2}{c}{\multirow{7}{*}{Frequency}} 
\\
\rotatebox{90}{Col1} & \rotatebox{90}{A} & \rotatebox{90}{BBBBB} 
  & \rotatebox{90}{CCCCCC} & \rotatebox{90}{DDDDD} & Abs. & Rel. \\
\midrule
1&9&8&7&6&5&4 \\
\bottomrule
\end{tabular}
\end{table}

\end{document}
