What Are Tables?
Tables are structured arrangements of data consisting of rows and columns. They are commonly used in various fields, including statistics, computing, and everyday life, to present information clearly and efficiently. A table helps in organizing data in a systematic manner, allowing for easier comparison and analysis.
Components of a Table
A typical table has several key components:
- Rows: Horizontal arrangements in the table that usually represent a single record or entry.
- Columns: Vertical arrangements that usually define the attributes or properties of the data.
- Cells: The boxes formed by the intersection of rows and columns that hold the actual data values.
- Header: The first row in a table that contains the names of the columns and defines what each column represents.
- Footer: The last row which may summarize the data in the table.
