Review comment (performance):
I noticed that you are calling `getValue` more than once, maybe should we cache it?  I realise this prevents the explicit return.  Additionally, might it make sense to create a component for this i.e `<UserAvatar displayName={displayname} />` incase we want to use it again?

Code after:
          header: t("rank"),
          cell: (ctx) =>
            ctx.row.original.isSpaceRow ? (
              <SpaceRow></SpaceRow>
            ) : isAdminOrMod ? (
              jsonExpandRowModel.renderCell(ctx)
            ) : (
              ctx.getValue()
            ),
        }),
        span: (cell) => (cell.row.original.isSpaceRow ? 6 : jsonExpandRowModel.span(cell)),
      },
      columnHelper.accessor("display_name", {
        header: t("user"),
        cell: ({ getValue, row }) => (
          <div className="flex flex-row items-center gap-2">
            <UserAvatar displayName={getValue()} avatarUrl={row.original.image}></UserAvatar>
            {isAdminOrMod ? (
              <Link as={NextLink} href={`/admin/manage_user/${row.original.user_id}`}>
                {getValue()}
              </Link>
            ) : (
              getValue()
            )}
          </div>
        ),
      }),
      columnHelper.accessor("leader_score", {

        header: t("reply"),
