this is the file address returned to me by the backend 

    h("a", {
                                props: {

                                },
                                domProps: {
                                    href: params.row.filepath,
                                    download: params.row.filename
                                },
                                style: {
                                    marginRight: "10px"
                                },
                            }, ""),
