When might you use a table in a document?

Using a table in a document is particularly effective for organizing complex data efficiently. Tables provide a structured format that allows for easy comparison and analysis of information, especially when dealing with multiple variables or categories. For instance, if you need to display sales figures across different regions or time periods, a table can clearly delineate the data points, making it much easier for readers to interpret the information at a glance.

The other options do not leverage the full functionality of tables. For instance, while background colors can enhance the visual appeal of a document, they do not serve the primary purpose of a table. Summarizing narrative text typically relies on paragraph structure and bullet points rather than tabular formats, which are better suited for numerical or categorical data. Finally, formatting images is generally handled through different tools and settings that do not involve tables, which are specifically designed for organizing and displaying data in rows and columns.
