Table Borders do not display Properly

[MwlBrian]

Using latex code for an array to create a table, the lines do not display.

Sample code:
\begin{array}{r|l|}
\hline
\text{This}&\text{table}\\hline
\text{has}&\text{borders}\\hline
\end{array}

desired output (generated by codecogs)

Actual output using Better Math Equations:

When I originally noticed it, I was creating an array without outside borders and the inside borders did not appear.
I also just noticed that if I try to put outside vertical borders, by putting | in the beginning and end |r|l|, the app has an error and won't display the preview or generate the image with both borders. It works fine for r|l| and also for |r|l, but not for |r|l|
