Spreadsheet software like Microsoft Excel or Google Sheets organizes data into a grid of rows and columns.
A column is a vertical arrangement of cells — it runs from the top of the sheet to the bottom.
Columns are typically labeled alphabetically (A, B, C, ...) and help users identify and reference data vertically.
For example, all cells under column "B" are part of the same vertical line of data.
This contrasts with a row, which is a horizontal arrangement of cells labeled numerically (1, 2, 3, ...).
Thus, in vertical (standing) format, the correct answer is “column.”
