Issue #1355 - SetNeedToCalcHasBCBorders to true when initialize nsTableFrame

Browse source 
In the printing preview, we create continuous table frame if table is too long to containing in a page. But the default value of NeedToCalcHasBCBorders is false which means we don't calculate HasBCBorders for continuous table frame. Thus, the border collapse is not shown when printing preview.
