Value based styling for pivoted tables?

Question

What would you like to know?

Hi, not sure if I've missed something but is there an easy way to apply conditional styles (https://posit-dev.github.io/great-tables/get-started/basic-styling.html) to pivoted tables (ie. Dates as columns)?

I know it's possible to pass a polars column selector in the location body, but I haven´t found a proper way to select rows per column automatically.

Something like this

 tab_style(
        style=style.text(color="white"),
        locations=loc.body(
            columns=cs.numeric(),
            rows=pl.col("each-column-from-the-selector").eq(0)
        )
    )

The alternative is applying styles on individual columns but that's a bit cumbersome when columns are dynamic
