# Style Styles are built with `Vtiful\Kernel\Format` and applied to cells, rows or columns. A single `Format` handle can be reused across many cells. Pages in this section: * [Combination style](/english/style/combination.md) — chain multiple style methods on one handle. * [Global default style](/english/style/default-format.md) — apply a style to every cell of a worksheet. For the full catalogue of individual style attributes, see [Style list](/english/style-list.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
