Fix inline markup causing table cells to split

Before this change, markup inside a table cell would introduce a newline, which
resulted in those parts creating a new table row/cell:

       ┌───────────────────────────────┬───────────────────────────┐
       │Col1                           │ Col2                      │
       ├───────────────────────────────┼───────────────────────────┤
       │row|one                        │ Col1 should not wrap.     │
       ├───────────────────────────────┼───────────────────────────┤
       │row two                        │ no                        │
       ├───────────────────────────────┼───────────────────────────┤
       │|                              │                           │
       ├───────────────────────────────┼───────────────────────────┤
       │wrap                           │                           │
       ├───────────────────────────────┼───────────────────────────┤
       │row three                      │ Inline                    │
       ├───────────────────────────────┼───────────────────────────┤
       │cursive markup should not wrap │                           │
       ├───────────────────────────────┼───────────────────────────┤
       │row four                       │ Inline                    │
       ├───────────────────────────────┼───────────────────────────┤
       │code markup should not wrap    │                           │
       └───────────────────────────────┴───────────────────────────┘

After this change, markup does not introduce a newline, and content is correctly
rendered in a single table row / cell:

       ┌───────────────────────────────┬───────────────────────────┐
       │Col1                           │ Col2                      │
       ├───────────────────────────────┼───────────────────────────┤
       │row|one                        │ Col1 should not wrap.     │
       ├───────────────────────────────┼───────────────────────────┤
       │row two                        │ no|wrap                   │
       ├───────────────────────────────┼───────────────────────────┤
       │row three                      │ Inline cursive markup     │
       │                               │ should not wrap           │
       ├───────────────────────────────┼───────────────────────────┤
       │row four                       │ Inline core markup should │
       │                               │ not wrap                  │
       └───────────────────────────────┴───────────────────────────┘
