Interface DataGridColumn<T>

"num" right-aligns the header and cells and uses tabular figures (#58). Default left.

CSV value (#58): what the export writes for this column instead of the cell value, so a cell that renders a local name can export the full IRI. Quoted per RFC 4180 as needed.

Inline header filter kind. "text" is a substring match, "values" a checklist over the distinct values with counts (#47: several at once, exact match on the value's string form), "range" a numeric min/max pair, "none" no filter (and no cross-column search over it either). Omit it and the kind is INFERRED from the column's values (#58): "range" when every present value is a finite number (and there is at least one); "values" when the distinct string forms of the present values number at most 20 (VALUES_FILTER_MAX_DISTINCT) and at most half the present rows, so the checklist is shorter than the column it filters; "text" otherwise, including an empty table. Null and undefined do not count as present. An explicit kind always wins; the inference re-runs when rows changes, and a column whose inferred kind flips drops its filter value (the two kinds store different shapes). Rows path only: UGM columns stay "text".

Header text, also the label in the column-visibility menu.

Hidden by default (#58): the column starts toggled off in column visibility, so the column menu still lists it and the user can show it. A column that arrives hidden in a later column set is hidden too; a visibility change made by the user is kept.

Stable column id (test ids and visibility state key off it).

Renders the cell; defaults to the stringified value, with null/undefined shown as a dash. A table-wide renderCell that returns a non-undefined node takes precedence.

Header tooltip (#58): the title attribute on the sort trigger, for a longer description of a short header.

Reads the sortable, filterable value out of a row.

Column width (#58): px as a number, or any CSS width. Applied to the header cell; the table otherwise sizes to content.
