In davidgohel/officedown: Enhanced 'R Markdown' Format for 'Word' and 'PowerPoint'

a list that can contain few items to style tables and table captions. Missing items will be replaced by default values. Possible items are the following:

style: the Word stylename to use for tables.
layout: 'autofit' or 'fixed' algorithm. See \code{\link[officer]{table_layout}}.
width: value of the preferred width of the table in percent (base 1).
topcaption: caption will appear before (on top of) the table,
tab.lp: caption table sequence identifier. All table captions are supposed to have the same identifier. It makes possible to insert list of tables. It is also used to prefix your 'bookdown' cross-reference call; if tab.lp is set to "tab:", a cross-reference to table with id "xxxxx" is written as \@ref(tab:xxxxx). It is possible to set the value to your default Word value (in French for example it is "Tableau", in German it is "Tabelle"), you can then add manually a list of tables (go to the "References" tab and select menu "Insert Table of Figures").
caption; caption options, i.e.:
style: Word stylename to use for table captions.
pre: prefix for numbering chunk (default to "Table ").
sep: suffix for numbering chunk (default to ": ").
tnd: (only applies if positive. )Inserts the number of the last title of level tnd (i.e. 4.3-2 for figure 2 of chapter 4.3).
tns: separator to use between title number and table number. Default is "-".
fp_text: text formatting properties to apply to caption prefix - see [officer::fp_text_lite()].
conditional: a list of named logical values:
first_row and last_row: apply or remove formatting from the first or last row in the table
first_column and last_column: apply or remove formatting from the first or last column in the table
no_hband and no_vband: don't display odd and even rows or columns with alternating shading for ease of reading.

style: Table

width: 1.0
topcaption: true
tab.lp: 'tab:'
