Parse back from output doesn't work if comment is present

[teejay-87]

I think that parsing this

// ┌────┬───────┬───────┐
// │    │  OBJ  │  COM  │
// ├────┼───────┼───────┤
// │  1 │ S1    │ S1    │
// │ 12 │ S1+S2 │ S1+S2 │
// └────┴───────┴───────┘

should work if i set "Unicode (single line)" as output style and "C++/C#" as comment style.

I can confirm this issue.
