I have a better solution:
1. Put the following lines in the preamble:
\usepackage{array}
\newcommand{\arraylines}[1]{{\newcolumntype{r}{c|}#1}}
2. When you insert a matrix, use r alignment instead of c|, namely if
you want cc|c alignment, then write crc in the matrix dialog.
3. Put \arraylines{} around the whole math inset,
or inside the math inset, around the matrix
