RDLC 导出Word的时候发现，Word的尺寸和页边距有问题，查了MSDN看到这样一段话
Page Sizing
When the report is rendered, the Word page height and width are set by the following RDL properties: paper size height and width, left and right page margins, and the top and bottom page margins.
于是用记事本打开RDLC文件添加并修改以下参数的值
// 页边距
<RightMargin>0.5in</RightMargin>
<LeftMargin>0.5in</LeftMargin>
<TopMargin>0.25in</TopMargin>
<BottomMargin>0.25in</BottomMargin>
// 页的宽度和高度
<PageWidth>11in</PageWidth>
<PageHeight>8.5in</PageHeight>
一、取总条数和当前页数
"Page" & Str(Globals!PageNumber) & " Of "+Trim(Str(Globals!TotalPages))
