pbi desktop Color transparent option missing

In a table the rows by default can be alternatively white and grey because they have no background.
When the table is customized with many columns, each with custom background, if I want to remove the background of one column, there is not the 'No color' option, and the only solution is to set the full table design back to default. And then re color all the columns except the one that I wanted as transparent.

I would appreciate having a 'Transparent' option in the color palette.
