Tables containing links with aliases do not escape pipe.

[TheMathGuyd]

Importer has given me a table that fails to render because the links in it contained aliases.

Example of problematic output

| Col1             | Col2             |
|------------------|------------------|
| [[file1|alias1]] | [[file2|alias2]] |

Should have escaped pipes like:

| Col1              | Col2              |
|-------------------|-------------------|
| [[file1\|alias1]] | [[file2\|alias2]] |

(unless obsidian itself should render the links in table without escaped pipe; in which case, this is a different bug altogether)
