In the context of document formatting, what is 'merging' most likely associated with?

Merging is most commonly associated with joining cells in a table within document formatting. This process allows multiple adjacent cells in a table to be combined into a single cell, which can be useful for creating headings or organizing data more effectively. When cells are merged, it simplifies the table structure and enhances the visual representation of information, making it easier for readers to process.

The other contexts mentioned, such as combining document sections or connecting headings to body text, do not specifically refer to the merging process. Blending colors in text pertains to formatting styles but does not involve the concept of merging in the same way as table cells do. Therefore, merging is distinctly relevant to table management in document formatting.
