A conditional formatting rule’s condition — only cellIs (a direct value comparison) and expression (an arbitrary custom formula) are modeled, CT_CfRule’s two simplest and most common types.

Variants

CellIs

type="cellIs": compares the cell’s own value against one or two formulas using a relational operator (e.g. “greater than 0.5”, or “between 10 and 20” when formula2 is set).

Fields

operator: ComparisonOperator

formula1: String

The first (or only) comparison value/formula.

formula2: Option<String>

The second comparison value/formula — only meaningful (and required by Excel) for Between/NotBetween.

Expression

type="expression": an arbitrary formula, evaluated per cell in range, with the format applied when it evaluates to TRUE.

Fields

formula: String

The formula text (e.g. "MOD(ROW(),2)=0" for zebra striping).

ColorScale(Vec<ColorScaleStop>)

A 2- or 3-stop color scale (<colorScale>, CT_ColorScale). Unlike every other condition variant, a color scale ignores ConditionalFormattingRule::format entirely (its coloring comes from the stops themselves, not a dxf) — the writer never allocates a dxfId for this variant, see writer.rs::write_conditional_formatting.

DataBar

A data bar (<dataBar>, CT_DataBar) — min/max stops plus a single fill color. Like ColorScale, ignores format.

Fields

min: CfvoPosition

max: CfvoPosition

color: String

IconSet(IconSetType)

A 3-icon set (<iconSet>, CT_IconSet) using Excel’s own default equal-thirds percent thresholds (0/33/67) — only the icon set’s visual style is configurable, not custom thresholds (out of scope). Like ColorScale, ignores format.

Top10

type="top10": highlights the top (or bottom) rank items/percent of range.

Fields

rank: u32

percent: bool

Whether rank is a percentage rather than a raw count.

bottom: bool

Highlights the bottom rank instead of the top.

AboveAverage

type="aboveAverage": highlights cells above (or below) the range’s average.

Fields

above: bool

Highlights above-average cells (true) or below-average ones (false).

equal_average: bool

Also highlights cells exactly equal to the average.

DuplicateValues

type="duplicateValues": highlights cells whose value appears more than once in range.

UniqueValues

type="uniqueValues": highlights cells whose value appears exactly once in range.

ContainsText

type="containsText"/"notContains"/"beginsWith"/"endsWith" (four distinct CT_CfRule types sharing the same shape, see TextComparisonOperator): highlights cells whose text matches text per operator. Unlike ConditionalFormattingCondition::CellIs, Excel auto-generates the underlying formula from text and the range’s first cell — this crate reproduces that (see writer.rs::write_conditional_formatting), it isn’t the caller’s formula to write.

Fields

operator: TextComparisonOperator

text: String
