I would like to draw table,

I tried,
\begin{equation}
\begin{array}{c}
z \\
s_1 \\
s_2 \\
s_3
\end{array}
\begin{bmatrix}
\begin{array}{c|ccccc|c}
z & x_1 & x_2 & s_1 & s_2 & s_3 & b \\ \hline
1 & 0 & 0 & 1.6 & 2.2 & 0 & 544 \\ \hline
0 & 1 & 1 & 0.4 & -0.2 & 0 & 16 \\
0 & 0 & 1 & -0.2 & 0.6 & 0 & 72 \\
0 & 0 & 0 & -0.4 & 0.2 & 1 & 19 \\
\end{array}
\end{bmatrix}
\end{equation}
However I get, with an allignment issue on the left,

\kbordermatrixto label the columns as well as rows instead. – OJFord Nov 18 '15 at 07:06
