Conditional formatting not working for single row .

Hi,

According to your description, I think that any table which doesn't have a grouping displayed as a single row doesn't support conditional formatting.

Reference:

https://docs.microsoft.com/en-us/power-bi/desktop-conditional-table-formatting#considerations-and-limitations

And I have a workaround for your problem, so I create a table to test:

please take following steps:

1)Create a measure to minus [Actual] and Budget:

Measure = SUM('Table'[Actual])-SUM('Table'[Budget])

2)Create a measure to define font format and apply it to above measure:

Format = SWITCH(true,[Measure]>0,"#FF0000",[Measure]<0,"#008000")

And it shows:

3)Add a column and change it not summarize:

When you remove [Department], it shows:

if you do not want to display the blank column, you can turn off ‘Word wrap’ function in visual format/column headers:

And it shows:

Here is my test pbix file:
