hi i try use Conditional Format
Is it way change font for date column?
You want to change the font based on what exactly? I can't read cyrilic so no idea what you're doing from your screenshot
font color must change (on DATE column) when value of other column is 'Y'
So table is cross-table.
I assume you added that condition on the date column based on the value of the other column = 'Y' and it didn't work?
Or I'm just not getting what you are asking for
I added condition on date column. I want change color/font when other column is 'Y'. It's not working! Why?
Can you try to exchange the 2 columns? So put the Y/N above and the date below? (just to check your rules are fine)
Is the column with Y/N really useful on the screen or you just used to have a flag (Y or N) for the conditional formatting?
I think you are facing issue as described in below mentioned blog, but there is no reason mentioned for such a behavior:
