I know this should be simple, but my head won't work this out!
In Row 1 I have months
In Column A I have dates of work started
What I need is conditional format to "grey out" the cell if the date in column A is before the start date of the month
So if the date was 02/04/19 it will leave the April column blank,
if it was 2 May 2019, it would grey out April, but leave May 2019 blank,
if it was June, then both April and May would be greyed out etc.
