For vec_nlines, calculate the number of lines each element of a column vector will
take to render. For format_colvector,
format_colvector(df, colnm, colvec = df[[colnm]])vec_nlines(vec, max_width = NULL, fontspec = dflt_courier)
# S4 method for ANY
vec_nlines(vec, max_width = NULL, fontspec = dflt_courier)
(numeric)
a vector of the number of lines element-wise that will be
needed to render the elements of vec to width max_width.
(listing_df)
the listing.
(string)
column name.
(vector)
column values based on colnm.
(vector)
a vector.
(numeric(1) or NULL)
the width to render the column with.
