Column

/ˈkäləm/

noun

1. a supporting pillar
If you look at Gothic detail right down to the bottom of a column, it’s a small version of the whole building— that’s why, like dating the backbones of a dinosaur a good historian can look at a detail of a Gothic building and tell you exactly what the rest of the building was, and infer the whole from the parts.
– Charles Jencks, (1939-2019)

2. a section of text in a book, newspaper, magazine or website regularly devoted to a specific subject or written by a particular person
The advertisements in a newspaper are more full of knowledge in respect to what is going on in a state or community than the editorial columns are.
– Henry Ward Beecher, (1813-1887)

3. a vertical division of a page or text
The body tends to treat elements in the same column of the periodic table as equivalents.
– Sam Kean
