Fixing Invalid Syntax Crash. (#164)

There is no check for rows count which is unsafe currently.
If this is not changed the builder crashes for this example:
```
Pr(H | E) \text{ is the probability that the the hypothesis } H \text{ is true given evidence } E \text{ is true} \\
Pr(H) \text{ is the probability that the hypthesis } H \text{ is true prior to } E \\
Pr(\neg H) \text{ is the probability that } H \text{ is false prior to } E \\
Pr(E\vert H) \text{ is the probability ) E \text{ is true given } H \text{ is true} \\
Pr(E\vert\neg H) \text{ is the probability } E \text{ is true given } H \text{ is false} \\```
