Parser fails on tables with indentation colons

[gartentrio]

Tables with leading indentation colons are not parsed correctly.
See example from article https://de.wikipedia.org/wiki/Actinium?action=raw:

Another example is "Komplette Fortschrittstabelle" at
https://de.wikipedia.org/w/index.php?title=Schacholympiade_1994&oldid=161991782

Here, the table was also indented (probably for aesthetic reasons), with :{|, and it appears as if Sweble does not recognize and parse this table.
