Issue Description

If I escape the pipe symbol in a table, the SpecFlow syntax highlighter gets confused.

Steps to Reproduce

Then the data should be
    | Field     | Value    |
    | SomeField | a\|b\|c  |

Notice that the b in the table and everything to the right of it is colored black.
I expected only the non-escaped pipe symbols to be colored black in that row.

Thank you.

Interesting. TBH I didn't know you can escape the pipe in a table.
