如何解决EXCEL上传函数ALSM_EXCEL_TO_INTERNAL_TABLE的重新封装问题
这篇文章主要介绍了如何解决EXCEL上传函数ALSM_EXCEL_TO_INTERNAL_TABLE的重新封装问题，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。
ALSM_EXCEL_TO_INTERNAL_TABLE有两个限制：
每个CELL只能导入前50个字符；
如果超过9999行，行号会初始化为从零开始
解决办法：
COPY ALSM_EXCEL_TO_INTERNAL_TABLE 为 ZALSM_EXCEL_TO_INTERNAL_TABLE ，并做少许改动即可
定义结构新的返回ZSALSMEX_TABLINE
函数输入输出
代码如下（定义与ZEXCEL自定义函数组下，便于代码管理）：
function zalsm_excel_to_internal_table.
