I'm here again with probably silly questions... :( I have a JTable I wish to filter out as I type on a textfield. After researching a bit I came up with this, but it doesn´t work! If I put the filter outside the listener with an arbitrary string as search term it works perfectly. What am I missing? Thank you!

So I ended up getting it started. Looks like a simple mistake. You forgot the setRowSorter for the table.
searchTable.setRowSorter(sorter);
Added that code an it works for me. Should work for you two, give you have a valid TableModel passed to the GUI. I just made up a dummy one.
NOTES:
You'll probably want to add the filter code to removeUpdate also, in the DocumentListener so when text is backspace'd, it will still filter.
This searchTable.getColumn("Key").setMaxWidth(0); makes the row data not visible. Is that what you really want?
If you want the filter to filter without case-sensitivity, you can use this
sorter.setRowFilter(RowFilter.regexFilter("(?i)" + searchText));
The "(?i)" is the case-insentive regex "flag"
