To be able to set separate column header (and whole columns) backgrounds in a matrix to a specific color based on its value (Same as conditional formatting of values by field value) for multi-column ...
Totally agree with this, I think column headers should have all the conditional formatting options and tooltips in the same way the values do.
There should also be the option to unfreeze the column headers and keep them unfrozen during publishing.
I often have very wide matrix tables and need to put a lot of data in the rows because of the parent/child relationships where you want text displayed without summarising and without repeating the rows as in a standard table.
