# Dividers

 Dividers is an option for Grid and related constructs that specifies where and how to draw divider lines.
• The following basic settings can be given:
 All draw all dividers None or False draw no dividers True draw dividers around the exterior only Center draw dividers between interior items only g draw all dividers using graphics directive g
• For Grid and related constructs, lists of settings can be given. Common cases include:
 {All,False} put dividers at every horizontal position (column lines) {False,All} put dividers at every vertical position (row lines) {{False,True},False} put a divider before the second column {False,{False,True}} put a divider before the second row
• General settings for Dividers in Grid and related constructs can be given as:
 {specx,specy} use the speci at successive x and y positions
• The speci can have the following forms:
 {s1,s2,...,sn} use s1 through sn; then use defaults {{c}} use c in all cases {{c1,c2}} alternate between c1 and c2 {{c1,c2,...}} cycle through all ci {s,{c}} use s, then repeatedly use c {s1,{c},sn} use s1, then repeatedly use c, but use sn at the end {s1,s2,...,{c1, c2, ... }, sm, ... , sn} use the first sequence of si at the beginning, then cyclically use the ci, then use the last sequence of si at the end {s1,s2,...,{},sm,...,sn} use the first sequence of si at the beginning and the last sequence at the end {i1->v1,i2->v2,...} specify what to use at positions ik { spec,rules} use rules to override specifications in spec
• The si and ci can be True, False, or an explicit graphics directive.
• Possible graphics directives include Thick, Thin, Dashed, Dotted, as well as color, thickness and dashing directives, and composite directives specified by Directive.
• For a grid with n items in a particular direction, Dividers can specify settings for dividers in the gaps between items, starting before the first element, and ending after the last element.
• Dividers are always placed at the center of the gaps between items.
• Dividers never extend into items that span rows or columns.
Draw all the interior dividers in a grid:
Put dividers at all horizontal positions:
Draw all the interior dividers in a grid:
 Out[1]=

Put dividers at all horizontal positions:
 Out[1]=
 Scope   (3)
Put dividers at the third horizontal and second vertical positions:
Draw a divider at every other horizontal position:
Include the final position:
Draw dividers with specified styles:
Dividers acts in addition to any Frame specification:
FrameStyle will set the default style for all lines in the grid:
