How to make a table span two columns for Oxford Bioinformatics Journal template?

I am using the latest Latex template provided by the Oxford bioinformatics Journal. I want a table to span over the two columns. I found some questions on stackexchange about figures and tried to apply the same logic to my table but it does not work. Is there any way to make my table span over two columns? My actual table is a lot bigger than the example given here which is why I need it to be larger than one column.

When I use the "table*" environment my table disappears completely and when I use "tabular*" I get a lot of errors. I am kind of new to Latex and hope that you can help me.
