R gt package - How to rename all columns at once

I have a dataframe like this one:

library(gt)
library(tidyverse)
library(gtExtras)

test = dplyr::tibble(
  id = 1:3,
  type1_value1 = 2:4,
  type1_value2 = 3:5,
  type2_value1 = 4:6,
  type2_value2 = 5:7)

I actually want to have only spanners but no col_lables, which doesnt seem to work, when I try it:

test %>%
  gt() %>%
  tab_spanner(
    label = "span1",
    columns = c(2:3)) %>%
  tab_spanner(
    label = "span2",
    columns = c(4:5)) %>%
  tab_options(column_labels.hidden = TRUE)

The spanners just wont appear. If you know any solution what is wrong, please give me a hint. I tried to work around it now by just renaming every column with no name.

test %>%
  gt() %>%
  tab_spanner(
    label = "span1",
    columns = c(2:3)) %>%
  tab_spanner(
    label = "span2",
    columns = c(4:5)) %>%
  cols_label(id = "", type1_value1 = "", type1_value2 = "", 
             type2_value1 = "", type2_value2 = "") 
  
  cols_label(id = "", type1_value1 = "", type1_value2 = "", 
             type2_value1 = "", type2_value2 = "") 

My real df has over 200 columns. How can I rename them all at once? They should all get the empty name "".

Thanks for any help.

Using the tidyselect helper everything() you could rename all columns at once like so:

library(gt)
library(tidyverse)

test %>%
  gt() %>%
  tab_spanner(
    label = "span1",
    columns = c(2:3)
  ) %>%
  tab_spanner(
    label = "span2",
    columns = c(4:5)
  ) %>%
  cols_label(
    everything() ~ ""
  )
