Matrix column sorting & formatting

[101Mathew]

There appears to be no method to format column vertical lines; i would love to be able to format the top level of a column hierarchy - to have a alternating colour background on the that level of text, also to have thicker vertical lines

It also seems mad that we don't appear to have a method to sort the column order

These issues are made worse if you need to switch the measure to rows (which is rather common)
