Data tables are organized structures that display information in rows and columns, making it easy to read and analyze data. Each row typically represents a single record or entry, while each column contains specific attributes or variables related to that data. For example, a data table about students might include columns for name, age, and grade. These tables are commonly used in various fields, including business, science, and education, to present data clearly. They help users quickly identify patterns, trends, and relationships within the data, facilitating better decision-making and understanding of the information presented.
