```

Rule is a vector or colors of length 2 or 3 (any hex color or any of `colors()`).
If rule is `NULL`, min and max of cells is used. Rule must be the same length as style or L.

```{r eval=FALSE}
wb$add_conditional_formatting(
  sheet = "colorScale",
  dims = wb_dims(
    rows = seq_len(nrow(df)),
    cols = seq_len(ncol(df))
    ),
  # dims = wb_dims(x = df, col_names = FALSE, select = "data")
  style = c("black", "white"),
  rule = c(0, 255),
  type = "colorScale"
)

wb$set_row_heights("colorScale", rows = seq_len(nrow(df)), heights = 7.5)
```
