Concatenate all Strings in a column into a new string

Hi,

is it possible to join/concatenate all Strings in a column to create a new String in KNIME?

I know that the `Math Formula` node can do mean/max/min/sum/... over an entire column. Is there also something like this for strings?

Or, to ask in even more general terms: Is there something like a `reduce` function for columns in Knime? Many nodes perform `map` functions, but having both `map` and `reduce` would be really helpful.

The groupby node with no grouping columns specified will group the entire table to a single group.  Then you can choose concatenate as the operation for the collumn you want
