The part of a table that describes the main categories of information is known as Column headers.

Explanation

In a table, column headers are typically located at the top of each column and provide a concise description of the data contained in that column. They serve as a guide to help readers understand what type of information is being presented. For example, if a table displays data about a group of students, the column headers might include categories such as "Name," "Age," "Grade," and "City." Each header indicates the specific type of information that corresponds to each row in the table.

In contrast, row titles (or row headers) identify individual records and categorize the data across the different columns, while the table title summarizes the overall content of the table. Therefore, while all these elements are essential for organizing information effectively, the column headers specifically denote the main categories of information in the table itself.
