ConTeXt 中的表格存在问题

我在使用 \bTABLE \eTABLE 创建表格时遇到问题。创建 14 行（每行 6 列）后，出现以下错误：

luatex warning  > nodes: node 53798 has an attribute list that is free already, case 1
! error:  (nodes): trying to delete an attribute reference of a non attribute nodemtx-context     | fatal error: return code: 256

我的源文件中的表格如下所示（仅显示几行“数据”）：

我被困住了 ;-(

非常感谢你的帮助，J

我没有看到你的错误。但你的代码似乎是错误的。你确实

\startplacetable[...]{
  ...
}

使用下面的代码我没有收到任何错误。

   reference=u0:prefixes,
