Time Table in Latex

Question

Could some one guide me in making this table in Latex? I am new to programming and I couldn't go through to this because of my poor programming skills.

Edited: Could someone fix the last column in last row which shows "Cancelled"?

Here is my coding,

\begin{tabular}{|l|c|l|c|l|c|l|} \hline

&\multicolumn{2}{||c|}{6.15-7.15 pm}
&\multicolumn{2}{|c|}{7.20-8.20 pm}
&\multicolumn{2}{|c||}{8.30-9.30 pm}\\ \hline \hline

\multirow{3}{*}{Day} &\multirow{3}{*}{Subj.} &Teacher & &Teacher &\multirow{3}{*}{Subj.}&Teacher\\ \cline{3-3} \cline{5-5} \cline{7-7}& &Room
&\multirow{1}{*}{Subj.} &Room &  &Room \\ \hline

\multirow{3}{*}{Mon} &\multirow{3}{*}{UNIX} &Dr. Smith & &Ms. Clarke  &\multirow{3}{*}{Math.}&Mr.Mills\\ \cline{3-3} \cline{5-5} \cline{7-7} & &Comp. Ctr
&\multirow{1}{*}{Fortran} &Hall A &  &Hall A \\ \hline

\multirow{3}{*}{Tues} &\multirow{3}{*}{LaTex} &Miss Baker & &Ms. Clarke  &\multirow{3}{*}{Math.}&Mr.Mills\\ \cline{3-3} \cline{5-5} \cline{7-7} & &Conf. Room
&\multirow{1}{*}{Fortran} &Conf.Room &  &Hall A \\ \hline

\multirow{3}{*}{Wed} &\multirow{3}{*}{UNIX} &Dr. Smith & &Dr. Jones &\multirow{3}{*}{ComSci}&Dr.Jones\\ \cline{3-3} \cline{5-5} \cline{7-7} & &Comp. Ctr
&\multirow{1}{*}{C} &Hall B &  &Hall B \\ \hline

\multirow{3}{*}{Fri} &\multirow{3}{*}{LaTex} &Miss Baker & &Ms. Clarke  &\multirow{3}{*}{Cancelled } & \\ \cline{3-3} \cline{5-5} & &Conf. Room &\multirow{1}{*}{C++} &Conf.Room &  &  \\ \hline

\end{tabular}

Answer 1

Is it something like that you want?

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{array, multirow}

\newlength{\lA}\settowidth{\lA}{ComSci}
%\setlength{\lA}{2cm}
\newlength{\lB}\settowidth{\lB}{Conf. Room}

\usepackage{cellspace}
\setlength\cellspacetoplimit{6pt}
\setlength\cellspacebottomlimit{4pt}

    \multicolumn{1}{c|}{} & \multicolumn{2}{@{\,}|Sc|}{6.15-7.15 pm}
