vue+typescript Property 'toggleR

看一下写法，会报错

private toggleSelection(rows: any) {
        rows.forEach((row: any) => {
        this.$refs.articleTable.toggleRowSelection(row);
        })
    }

修改为以下

private toggleSelection(rows: any) {
        const form = this.$refs.articleTable as ElTable
        rows.forEach((row: any) => {
            form.toggleRowSelection(row);
        })
    }
