w:cnfStyle (Conditional Table Formatting Reference)

Specifies which conditional formatting components of a table or list style apply to the current element.

Parent elements

Description

w:cnfStyle (conditional formatting style) is a 12-bit mask that indicates which conditional formatting components from a table style or list style are active for the current element. The bits correspond to specific parts of the style (first row, last column, odd/even bands, etc.).

It is defined in ECMA-376 Part 1 §17.3.1.8 (paragraph context) and related sections for other parent elements.

Consumers use w:cnfStyle to apply the correct conditional formatting from the referenced style without recomputing the mask. The element is normally generated automatically by producers (editors) when a style is applied — it is rarely authored manually.

Notes

The w:cnfStyle element is informational for consumers. The actual style definitions live in the table style’s w:tblStylePr child elements.
Do not confuse with w:style (applied named style) or w:pStyle (paragraph style).
