Give a color to the text according to some expression

rule_text_color(x, columns, expression, na.color = "", lockcells = FALSE)

Arguments

x

A condformat object, typically created with condformat()

columns

A character vector with column names to be coloured. Optionally tidyselect::language() can be used.

expression

lockcells

logical value determining if no further rules should be applied to the affected cells.
