If you have a cell in a table with a carriage return and an empty line the conversion to WYSIWYG fails. Here is an example of that failure.
{table}
Title 1|Title 2
abcd |abcd
{table}
- an empty line in a table fails to convert to wysiwyg from the wiki syntax
{table}
|{table}
now when type a block
{table}Title 1|Title 2
abcd |abcd
{table}
this syntax is converted to
{table}Title 1|Title2
abcd|abcd{table}
