Lists, rows and columns​

Row places expressions from the list in a row. Any strings are converted to normal text by the default

Row[{1, "->", 2}]
(*GB[*){{1(*|*),(*|*)"->"(*|*),(*|*)2}}(*]GB*)

Any expressions are valid

Column[{Red, Blue}]
(*GB[*){{(*VB[*)(RGBColor[1, 0, 0])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeGJAIcndyzs/JLwouTyxJzghJzS3ISSxJTWMGyXMgyRcxgMEHeyiDgQHOAAALpBNd"*)(*]VB*)}(*||*),(*||*){(*VB[*)(RGBColor[0, 0, 1])(*,*)(*"1:eJxTTMoPSmNkYGAoZgESHvk5KRCeGJAIcndyzs/JLwouTyxJzghJzS3ISSxJTWMGyXMgyRcxQAE644M9APZHE10="*)(*]VB*)}}(*]GB*)

Grid is a low-level primitive to construct tables

Grid @ Table[KroneckerDelta[i,j], {i,3}, {j,3}]
(*GB[*){{1(*|*),(*|*)0(*|*),(*|*)0}(*||*),(*||*){0(*|*),(*|*)1(*|*),(*|*)0}(*||*),(*||*){0(*|*),(*|*)0(*|*),(*|*)1}}(*]GB*)

Grids can be stylized using Item (accepts the same options as Style)

au = {{1, 2}, {3, 4}};
