Adding sort icon in react
Solution 1:
I saw your path was rendered twice, Im afraid if the first render is undefined, thus it return error.
To solve this error you may add this to your function:
renderSortIcon = column => {
const {sortColumn} = this.props
if (column?.path !== sortColumn?.path) return null;
if (sortColumn?.order === "asc") return <i className="fa fa-sort-asc" />;
return <i className="fa fa-sort-desc" />;
};
