Which dialog box in Word allows you to customize column settings?

The Columns dialog box is specifically designed for customizing column settings in Word. When you access this dialog box, you can adjust various aspects of the columns, including the number of columns, their width, and the spacing between them. This level of customization is essential for creating documents with multi-column layouts, such as newsletters or articles, where proper formatting can significantly enhance readability and presentation.

In contrast, the other dialog boxes mentioned serve different purposes. The Page Layout dialog box deals with overarching document layout settings, such as margins and page orientation, rather than specifically focusing on columns. The Format Cells dialog box is not relevant in Word; it applies primarily in spreadsheet applications like Excel to control the appearance of cells. Finally, the Table Properties dialog box is used to manage settings related to tables, such as alignment and cell size, rather than to customize the column layout of regular text. Thus, the Columns dialog box is the appropriate choice for tasks directly involving column management.
