I want to create the following block matrix
So far I have obtain the following matrix
\[
\renewcommand{\arraystretch}{1.3}
\left[
\begin{array}{c@{}c:c:c:c:c:c}
& \pmb{\Phi}_{1} & \pmb{\Psi}_{1} & \mathbf{0} & \cdots & \mathbf{0} & \mathbf{0} \\ \hdashline
& \mathbf{0} & \pmb{\Phi}_{2} & \pmb{\Psi}_{2} & \cdots & \mathbf{0} & \mathbf{0} \\ \hdashline
& \vdots & \vdots & \vdots & & \vdots & \vdots \\ \hdashline
& \mathbf{0} & \mathbf{0} & \mathbf{0} & \cdots & \pmb{\Phi}_{n-1} & \pmb{\Psi}_{n-1} \\ \hdashline
& \mathbf{0} & \mathbf{0} & \mathbf{0} & \cdots & \mathbf{0} & \pmb{\Phi}_{n} \\
\end{array}\right]
\]
It produces the following matrix
How can I achieve that the vertical line are not draw through in the third line like the matrix at the top?
