Function: column_getAutoSortDir()#

function column_getAutoSortDir<TFeatures, TData, TValue>(column): "asc" | "desc";

Defined in: features/row-sorting/rowSortingFeature.utils.ts:181

Chooses the default first sort direction from sampled filtered row values.

The first non-nullish value among the sampled rows decides: string columns start ascending so alphabetical order is natural; other value types (or columns with no non-nullish sample) start descending. Sampling past leading nullish values keeps the toggle cycle stable when sorting or a data swap moves an empty value into the first row.
