Algorithm for table layout
When a table is displayed in a document, it can either be displayed using a fixed width or autofit layout algorithm:
fixed: uses fixed widths for columns. The width of the table is not changed regardless of the contents of the cells.
autofit: uses the contents of each cell and the table width to determine the final column widths.
table_layout(type = "autofit")
| type | 'autofit' or 'fixed' algorithm. Default to 'autofit'. | 
Other functions for table definition: 
prop_table(),
table_colwidths(),
