you don't have keys in few place in this code.. e.g
{ headergroup.headers.map((column) => (
<th
classname={`p-2 table-header ${headercolor ? "primary-" + headercolor : "primary-deq"}`
{...column.getheaderprops()}
another problem may be that your keys are not unique. when you use map you can use the second parameter which is the iteration number, this will guarantee that your keys will be unique. e.g
{headergroups.map((headergroup, i) => ( <tr {...headergroup.getheadergroupprops()} key={i}> ...
// i instead of headergroup.id is unique
score:1
you need to add key
props in each mapping. for e.g
{headergroups.map((headergroup) => {
const { key, ...restheaderprops } = headergroup.getheadergroupprops();
return (
<tr key={key} {...restheaderprops}>
{headergroup.headers.map((column) => {
const { key, ...restcolumnprops } = column.getheaderprops();
return (
<th key={key} {...restcolumnprops}>
{column.render("header")}
</th>
);
})}
</tr>
);
})}
