IconStyleMatchMode
How the cell value should be matched against .
'Exact'(default) — strict===equality. Numbers, booleans and strings are matched as-is; useful when keys are tightly controlled. -'CaseInsensitive'— string keys are matched case-insensitively (cell value and key are both lowercased before comparison). Useful for free-typed columns where the same logical value can appear as'GBP'or'gbp'.
TypeScript
export type IconStyleMatchMode = 'Exact' | 'CaseInsensitive';
