我正在尝试暴露的ORM，但我得到了以下错误，我可怜的眼睛找不到原因：
线程“main”org.jetbrains.exposed.exceptions.DuplicateColumnException异常：表“Venues”中的列名“name”重复

object Organizations: IntIdTable() {
    val name: Column<String> = varchar("name", 255)
    val email: Column<String> = varchar("email", 255)
}

    val name: Column<String> = varchar("name", 255)
    val address: Column<String> = varchar("address", 255)

    val venue = reference("venueId", Venues)
