counting row entries


is there anybody who knows whether there is a Knime-node which is able to count the entries in a row of a table?

Thank you!

What do you mean by "couting the entries in a row"? You surely do not mean the number of columns, do you?


no, I don´t mean the number of the columns (sorry about my description).

I mean, if there are some cells of one row empty (in Knime shown as "?") and in another row there are entries in the cell (of the same column).

p.ex: column1  column2  column3

row1  aaaa       bbbb         ?              (2 entries)

row2  cccc         ?              ?              (1 entry)

row3  123         456           789          (3 entries)
