Stacks two or more gtsummary objects

Assists in patching together more complex tables. tbl_stack() appends two or more tbl_regression, tbl_summary, tbl_svysummary, or tbl_merge objects. Column attributes, including number formatting and column footnotes, are retained from the first passed gtsummary object.

tbl_stack(tbls, group_header = NULL)

Arguments

tbls	List of gtsummary objects
group_header	Character vector with table headers where length matches the length of tbls=

Value

A tbl_stack object

Example Output

Example 1

Example 2

  )

# Example 2 ----------------------------------
# stacking two tbl_merge objects

# first merging, then stacking
