---- Microsoft Excel 中内嵌的VBA为我们获取Excel文件信息提供了极大便利。通常,通过访问range对象,可以获得许多信息。访问分析表格的属性应从分析range开始。每一个range包括许多对象和属性,例如,font对象可以返回range的字体信息。通过遍历,即可获得整个表格信息。获取表格信息的目的在于准确地按照位置画表格线,同时确定文字位置。

---- (2).表格中表格文字位置的转换
---- 对文字对象的属性的直接控制来实现,通过with….end with 结构可以很容易地控制文字的高度、图层、颜色、书写方向。由于Mtext文字提供支持的排列位置分为9种,必须根据Microsoft Excel表格文字的排列方式加以合适的判定,然后进行转换。其具体的实现方法详见下面的程序。
