SpanFromLeft

SpanFromLeft

is a symbol that can appear at a particular position in a Grid or related construct to indicate that the corresponding position is occupied by a spanning element that appears to its left.

Details

  • If SpanFromLeft appears at several successive positions in a row, it indicates spanning across all these positions.

Examples

open all close all

Basic Examples  (4)

Make the element 4 span the column to its right:

Wolfram Language code: Grid[{{1, 2, 3}, {4, SpanFromLeft, 6}, {7, 8, 9}}, Frame -> All]

Make it span two columns:

Wolfram Language code: Grid[{{1, 2, 3}, {4, SpanFromLeft, SpanFromLeft}, {7, 8, 9}}, Frame -> All]

Span across the remaining width of the grid:

Wolfram Language code: Grid[{{1, 2, 3, 4}, {5, SpanFromLeft}, {6, 7, 8, 9}}, Frame -> All]

Spanning in a GraphicsGrid:

Wolfram Language code: GraphicsGrid[{{1, 2, 3}, {4, SpanFromLeft, SpanFromLeft}, {7, 8, 9}}, Frame -> All]

Scope  (2)

Spanned elements inherit their styles:

Wolfram Language code: Grid[{{1, 2, 3}, {Item[4, Background -> Red], SpanFromLeft, SpanFromLeft}, {7, 8, 9}}, Frame -> All]
Wolfram Language code: Grid[{{1, 2, 3}, {4, SpanFromLeft, SpanFromLeft}, {7, 8, 9}}, Frame -> All, Background -> {Automatic, Automatic, {2, 1} -> Red}]

Graphics will default to filling the available space:

Wolfram Language code: GraphicsGrid[{{Graphics[Rectangle[]], Graphics[Rectangle[]]}, {Graphics[Rectangle[], AspectRatio -> .5], SpanFromLeft}}]

An explicit ImageSize setting will prevent this behavior:

Wolfram Language code: GraphicsGrid[{{Graphics[Rectangle[], ImageSize -> {100, 100}], Graphics[Rectangle[], ImageSize -> {100, 100}]}, {Graphics[Rectangle[], AspectRatio -> .5, ImageSize -> {100, 100}], SpanFromLeft}}]

Possible Issues  (2)

Spanning regions must be rectangular in shape:

Wolfram Language code: Grid[{{1, SpanFromLeft, 3}, {4, SpanFromAbove, 6}, {7, 8, 9}}, Frame -> All]

Use SpanFromBoth when spanning across both columns and rows:

Wolfram Language code: Grid[{{1, SpanFromLeft, 3}, {SpanFromAbove, SpanFromBoth, 6}, {7, 8, 9}}, Frame -> All]
