## What's the maximum number of column for a row?

Implementations of [Row](http://cchantep.github.io/acolyte/apidocs/acolyte/Row.html) and [RowList](http://cchantep.github.io/acolyte/apidocs/acolyte/RowList.html) are provided up to 26 columns.
Implementations of [Row](http://cchantep.github.io/acolyte/apidocs/acolyte/Row.html) and [RowList](http://cchantep.github.io/acolyte/apidocs/acolyte/RowList.html) are provided up to 52 columns.

As Scala tuples are limited to 22, syntax `rowList :+ tuple` is not available above this limit.
