Rows and columns are used to describe the arrangement of sets of data or objects in space, but the difference between these two terms lies is the orientation of the objects. A row has the objects arranged horizontally, and a column has the objects arranged vertically.
In addition to being math terms, the words row and column have other definitions that incorporate the same spatial characteristics as their mathematical definitions. For example, in architecture, columns are arranged vertically to help support the overall structure of a building. In gardening, rows of vegetables in a field are spread horizontally across the ground.
