What is a Column?

  1. Basic Concept
    • A “column” refers to the vertical sections of a table. It’s essentially a vertical series of data.
  2. Example
    • Think of a spreadsheet application like Excel. If you look at the top of the sheet, you’ll see labels like “A,” “B,” and “C.” These labels denote columns. So, a column is a vertical grouping of data in a table.
  3. In Databases
    • In databases, columns are used in tables to represent different fields. For example, consider the following table:
    • This table has three columns: “Name,” “Gender,” and “Age.” Each column represents a different attribute or field of the data.
  4. In Layouts
    • In website or blog design, “column” is used to describe the layout structure. For example, “2-column layout” or “3-column layout” refers to the number of vertical sections in the design. A “2-column layout” means there are two vertical sections on the page.
