collapse_rows | R Documentation |
Collapse same values in columns into multirow cells. This
feature does similar things with group_rows
. However, unlike group_rows
,
it analyzes existing columns, finds out rows that can be grouped together,
and make them multirow cells. Note that if you want to use column_spec
to
specify column styles, you should use column_spec
before collapse_rows
.
collapse_rows(
kable_input,
columns = NULL,
valign = c("middle", "top", "bottom"),
latex_hline = c("full", "major", "none", "custom", "linespace"),
row_group_label_position = c("identity", "stack", "first"),
custom_latex_hline = NULL,
row_group_label_fonts = NULL,
headers_to_remove = NULL,
target = NULL,
col_names = TRUE,
longtable_clean_cut = TRUE
)
kable_input |
Output of |
columns |
A numeric value or vector indicating in which column(s) rows need to be collapsed. |
valign |
Select from "top", "middle" (default), "bottom". The reason why
"top" is not default is that the multirow package on CRAN win-builder is
not up to date.
Only used when |
latex_hline |
Option controlling the behavior of adding hlines to table.
Choose from |
row_group_label_position |
Option controlling positions of row group
labels. Choose from |
custom_latex_hline |
Numeric column positions whose collapsed rows will be separated by hlines. |
row_group_label_fonts |
A list of arguments that can be supplied to
group_rows function to format the row group label when
|
headers_to_remove |
Numeric column positions where headers should be removed when they are stacked. |
target |
If multiple columns are selected to do collapsing and a target column is specified, this target column will be used to collapse other columns based on the groups of this target column. |
col_names |
T/F. A LaTeX specific option. If you set |
longtable_clean_cut |
T/F with default T. Multirow cell sometimes are displayed incorrectly around pagebreak. This option forces groups to cut before the end of a page. If you have a group that is longer than 1 page, you need to turn off this option. |
