OK, I kind of have it working now (I think)…. probably more by circumstance than by design.

All I needed was to specify on the row with ‘equal_height=”1″‘ which is a good idea in my case anyway. So having <n> number of items I have a single row and <n> columns with the following definition:

[intense_column size="3" medium_size="4" small_size="6" extra_small_size="12"]

So in a large window I have 4 columns, then 3, then 2 and finally 1 when the window size is the smallest.

e.g. where X is a pricing table item
XXXX – Large
X

XXX – Medium
XX

XX – Small
XX
x

and all in a single column for extra-small.
