A data table is characterized by its structured organization, where each cell contains a single piece of information to avoid any ambiguity. The columns, essential for clarity, each have a defined type: text, number, date, etc. This ensures data consistency and facilitates processing. Numeric columns are right-justified for more intuitive reading, aligning the numbers and enabling quick comparisons. Additionally, having clear and explicit headers for each column is crucial, making the content easier to understand. Rows represent individual records, with each row containing all the information related to a single item. Finally, data normalization, such as using standard formats for dates and monetary values, is vital to prevent errors and inconsistencies.
