Stratigraphic column is just a synonym for geologic column.
Encyclopedia.com provides a more clear definition of stratigraphic column:
stratigraphic column1. A succession of rocks laid down during a specified interval of geologic time. The phrase ‘the stratigraphic column’ often refers to the whole sequence of strata deposited throughout geologic time.
2. A simplified columnar diagram relating a succession of named lithostratigraphic units from a particular area to the subdivisions of geologic time.
And here's the definition of lithostratigraphic unit:
lithostratigraphic unit (rock unit, rock-stratigraphic unit)
A body of rock forming a discrete and recognizable unit, of reasonable homogeneity, defined solely on the basis of its lithological characteristics (see LITHOLOGY). A lithological unit may be sedimentary, igneous, metamorphic, or a combination of these. As with other stratigraphic units, lithostratigraphic units are defined according to type sections. Their boundaries are placed at surfaces of lithologic change, usually sudden but sometimes gradational. As the physical nature of the units reflects depositional environments rather than time spans, the boundaries of lithological units may be diachronous. Lithostratigraphic units are comparatively local in extent when compared to the world-wide compass of chronostratigraphic units. They are ranked in decreasing order of magnitude in supergroups, groups, formations, members, and beds. A diverse, but distinctive and interrelated body of rock that cannot be subdivided into any other lithostratigraphic unit is termed a ‘complex’.
And as NoNukes pointed out, the definition at Wikipedia also includes igneous and metamorphic rock. You can't exclude them. If you use the term "geologic column" then igneous and metamorphic rock are part of geology and of course are part of the geologic column. And if you use the term "stratigraphic column" then igneous and metamorphic rock are strata and of course are part of the stratigraphic column.
Anywhere you stand on the Earth, the rocks beneath your feet all the way down to the mantle represent the geologic column at that location.
