Columns: Vertical lines that represent different categories of data, usually labeled with letters (A, B, C, etc.). Rows: Horizontal lines that represent individual data points related to the categories in the columns, usually numbered (1, 2, 3, etc.). Example: Imagine a spreadsheet tracking student information: Column A: Student Name Column B: Grade Level Column C: Math Score Each row would then contain the information for a single student, with their name in column A, grade level in column B, and math score in column C.
