Display options for tbl_df, used by trunc_mat() and
(indirectly) by print.tbl().
tibble.print_max: Row number threshold: Maximum number of rows
printed. Set to Inf to always print all rows. Default: 20.
tibble.print_min: Number of rows printed if row number
threshold is exceeded. Default: 10.
tibble.width: Output width. Default: NULL (use
width option).
tibble.max_extra_cols: Number of extra columns
printed in reduced form. Default: 100.
pillar.bold: Use bold font, e.g. for column headers? This currently
defaults to FALSE, because many terminal fonts have poor support for
bold fonts.
pillar.subtle: Use subtle style, e.g. for insignificant digits? Default:
TRUE.
pillar.neg: Highlight negative numbers? Default: TRUE.
pillar.sigfig: The number of significant digits that will be printed and
highlighted, default: 3. Set the pillar.subtle option to FALSE to
turn off highlighting of significant digits.
pillar.min_title_chars: The minimum number of characters for the column
title, default: 15. Column titles may be truncated up to that width to
save horizontal space. Set to Inf to turn off truncation of column
titles.
