How can I get '1', '2', '3', '4', and 'Supply' (i.e. the entries in the first row (but in different columns)) on the same height (vertical position) as 'Destination' (i.e. at the top of the columns instead of in the middle of the columns)?
Due to using the 'diagbox' option, the vertical position of these elements is off.

documentclass[12pt,fleqn]{article}

usepackage{pict2e}

usepackage{keyval}

usepackage{calc}

usepackage{fp}

usepackage{diagbox}

usepackage{booktabs}

usepackage{tabularx,colortbl}

begin{document}

begin{table}[h!]

  centering

  caption[caption]{Table 1}

  label{tab:table1}

begin{tabular}{|l|cccc|c|}

hline

diagbox{textbf{Source}}{textbf{Destination}} & $1$ & $2$ & $3$ & $4$ & textbf{Supply} \

hline

$1$ & $c_{11}$ & $c_{12}$ & $c_{13}$ & $c_{14}$ & $s_1$ \

$2$ & $c_{21}$ & $c_{22}$ & $c_{23}$ & $c_{24}$ & $s_2$ \

$3$ & $c_{31}$ & $c_{32}$ & $c_{33}$ & $c_{34}$ & $s_3$ \

$4$ & $c_{41}$ & $c_{42}$ & $c_{43}$ & $c_{44}$ & $s_4$ \

hline

textbf{Demand} & $d_1$ & $d_2$ & $d_3$ & $d_4$ & $T$\

hline

end{tabular}

end{table}

end{document}

meanwhile when you wait on desired solution, see if the following redesign of your table is acceptable to you:

documentclass[12pt,fleqn]{article}

%usepackage{pict2e}  % not needed in this mwe

%usepackage{keyval}  % not needed in this mwe

%usepackage{calc}    % not needed in this mwe

%usepackage{fp}      % not needed in this mwe

%usepackage{diagbox}

usepackage{booktabs,

            multirow,       % <--- new

            tabularx}

usepackage[table]{xcolor}



begin{document}

    begin{table}[h!]

caption[short caption]{long caption}

label{tab:table1}

    centering

begin{tabular}{*{6}{>{$}c<{$}} }

    toprule

multirow{2.4}{*}{textbf{Source}}

    & multicolumn{4}{c}{textbf{Destination}}

        & multirow{2.4}{*}{textbf{Supply}}    \

    cmidrule{2-5}

    &  1     & 2      & 3      & 4      &       \

    midrule

1   & c_{11} & c_{12} & c_{13} & c_{14} & s_1   \

2   & c_{21} & c_{22} & c_{23} & c_{24} & s_2   \

3   & c_{31} & c_{32} & c_{33} & c_{34} & s_3   \

4   & c_{41} & c_{42} & c_{43} & c_{44} & s_4   \

    midrule

textbf{Demand}

    & d_1    & d_2    & d_3    & d_4    & T     \

    bottomrule

end{tabular}

    end{table}

end{document}

edit: or you more prefer the following solution:

documentclass[12pt,fleqn]{article}

usepackage{diagbox}

usepackage{booktabs,

            makecell,   % <--- new

            multirow,   % <--- new

            tabularx}

usepackage[table]{xcolor}



begin{document}

begin{table}[h!]

  centering

  caption[caption]{Table 1}

  label{tab:table1}

begin{tabular}{|l|cccc|c|}

hline

multirow{2}{*}{

diagbox{textbf{Source}}{textbf{Destination}}

                }

    & $1$ & $2$ & $3$ & $4$ & textbf{Supply}   \

    &     &     &     &     &                   \

hline

$1$ & $c_{11}$ & $c_{12}$ & $c_{13}$ & $c_{14}$ & $s_1$ \

$2$ & $c_{21}$ & $c_{22}$ & $c_{23}$ & $c_{24}$ & $s_2$ \

$3$ & $c_{31}$ & $c_{32}$ & $c_{33}$ & $c_{34}$ & $s_3$ \

$4$ & $c_{41}$ & $c_{42}$ & $c_{43}$ & $c_{44}$ & $s_4$ \

hline

textbf{Demand} & $d_1$ & $d_2$ & $d_3$ & $d_4$ & $T$\

hline

end{tabular}

end{table}

end{document}

which gives:

it's probably not difficult to guess which solution I prefer ...

It is quite possible with some raiseboxes, but I don't think it's so nice:

documentclass[12pt,fleqn]{article}

usepackage{pict2e}

usepackage{keyval}

usepackage{calc}

usepackage{fp}

usepackage{diagbox}

usepackage{booktabs}

usepackage{tabularx,colortbl, makecell, caption}



begin{document}



begin{table}[h!]

  centering

  caption[caption]{Table 1}

  label{tab:table1}

begin{tabular}{|l|*{4}{>{$}c<{$}}|>{$}c<{$}|}

hline

diagbox[innerwidth =40mm, height =15mm]%,innerleftsep = 12pt

{raisebox{2.5ex}{textbf{Source}}}{raisebox{-0.5ex}{textbf{Destination}}} & raisebox{2.25ex}{$1$} & raisebox{2.25ex}{$2$} & raisebox{2.25ex}{$3$} & raisebox{2.25ex}{$4$} & raisebox{2.25ex}{textbf{Supply}} \

hline

1 & c_{11} & c_{12} & c_{13} & c_{14} & s_1 \

2 & c_{21} & c_{22} & c_{23} & c_{24} & s_2 \

3 & c_{31} & c_{32} & c_{33} & c_{34} & s_3 \

4 & c_{41} & c_{42} & c_{43} & c_{44} & s_4 \

hline

textbf{Demand} & d_1 & d_2 & d_3 & d_4 & T\

hline

end{tabular}

end{table}
