# set_borders

Draws borders around and/or inside a grid range. top/bottom/left/right are the range's outer edges; inner_horizontal/inner_vertical are the grid lines between cells inside it. Each side takes {style, color?} — styles SOLID, SOLID_MEDIUM, SOLID_THICK, DOTTED, DASHED, DOUBLE, or NONE to remove that side's border. Only the provided sides change; at least one is required. Colors are "#RRGGBB" hex (default black).
