大家好! 工作碰到一个问题:用ext grid显示ERP的单据(有表头表体或叫有分录或叫主表、附表的那种),但是这样所有的数据会一行一行的显示出来,所以想根据表头(或叫主表)字段来合并行,即相同的字段进行合并,比如第一行第一个字段是“小米”第一行第二个字段也是“小米”则只显示一个“小米”,网上找的大多是固定合并多少行的,我这个需求肯定是动态的,所以网上的那些不适用。 现在想征集大家的建议,看看有没有什么好的解决方案,而且最好能考虑速度!
回帖即给分,谢谢大家!

/*
**合并单元格的函数,合并表格内所有连续的具有相同值的单元格。调用方法示例:
**store.on("load",function(){gridSpan(grid,"row","[FbillNumber],[FbillDate],[FAudit],[FAuditDate],[FSure],[FSureDate]","FbillNumber");});
**参数:grid-需要合并的表格,rowOrCol-合并行还是列,cols-需要合并的列(行合并的时候有效),sepCols以哪个列为分割(即此字段不合并的2行,其他字段也不许合并),默认为空
