847 --[[ Options
848 ============
849 Container:
850 - columns ({col, col, ...}): Column settings. "col" can be a number (<= 0: content width, <1: rel. width, <10: weight, >=10: abs. width) or a table with column setting.
851 - space, spaceH, spaceV: Overall, horizontal and vertical spacing between cells.
852 - align, alignH, alignV: Overall, horizontal and vertical cell alignment. See GetCellAlign() for possible values.
853 Columns:
854 - width: Fixed column width (nil or <=0: content width, <1: rel. width, >=1: abs. width).
855 - min or 1: Min width for content based width
856 - max or 2: Max width for content based width
857 - weight: Flexible column width. The leftover width after accounting for fixed-width columns is distributed to weighted columns according to their weights.
858 - align, alignH, alignV: Overwrites the container setting for alignment.
859 Cell:
860 - colspan: Makes a cell span multiple columns.
861 - rowspan: Makes a cell span multiple rows.
862 - align, alignH, alignV: Overwrites the container and column setting for alignment.
