Java 下面的决策表可能有什么问题？

我现在只使用一条规则来实现这个决策表。我在规则“Screens_11”]中得到“输入不匹配”==，text=解析器返回了一个空包]]”错误。这是堆栈跟踪：

java.lang.RuntimeException: Error while creating KieBase[Message [id=1, level=ERROR, path=Sample.xls, line=8, column=0
   text=[ERR 102] Line 8:16 mismatched input '==' in rule "Screens_11"], Message [id=2, level=ERROR, path=Sample.xls, line=0, column=0
   text=Parser returned a null Package]]
    at org.drools.compiler.kie.builder.impl.KieContainerImpl.getKieBase(KieContainerImpl.java:450)
    at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:604)
    at org.drools.compiler.kie.builder.impl.KieContainerImpl.newKieSession(KieContainerImpl.java:575)
    at com.sample.TestDecisionTable.main(TestDecisionTable.java:15)

任何帮助都将不胜感激

编辑：添加从电子表格生成的文本

第8行已加入单元格。不要在约束列之外进行连接

请尝试此代码并返回完整输出

private void testSpreadsheet(){
  File dtf = new File( dtPath );
  InputStream is;
  try {
    is = new FileInputStream( dtf );
    SpreadsheetCompiler ssComp = new SpreadsheetCompiler();
    String s = ssComp.compile( is, InputType.XLS );
    System.out.println( "=== Begin generated DRL ===" );
    System.out.println( s );
    System.out.println( "=== End generated DRL ===" );
  } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
  }
}

提示：请不要涉足短屏幕业务。至少对于源代码：即文本；并且应该以这样的方式输入！提示：请不要涉足短屏幕业务。至少对于源代码：即文本；并且应该以这样的方式输入！补充问题。请检查。规则文本有助于查找错误。我把所有的条件语句都集中在一列中，结果成功了。我想知道怎样才能把所有的条件语句分开。谢谢你的提问。请检查。规则文本有助于查找错误。我把所有的条件语句都集中在一列中，结果成功了。我想知道怎样才能把所有的条件语句分开。谢谢
