SpreadJS provides nine alignment options by combination of two directions horizontal and vertical, allow you to show your data at proper position in the cell. Here is sample code how to show your data in different position in the cell:

sheet.getCells(1,1,1,3).vAlign($.wijmo.wijspread.VerticalAlign.top); sheet.getCells(2,1,2,3).vAlign($.wijmo.wijspread.VerticalAlign.center); sheet.getCells(3,1,3,3).vAlign($.wijmo.wijspread.VerticalAlign.bottom); sheet.getCells(1,1,3,1).hAlign($.wijmo.wijspread.HorizontalAlign.left); sheet.getCells(1,2,3,2).hAlign($.wijmo.wijspread.HorizontalAlign.center); sheet.getCells(1,3,3,3).hAlign($.wijmo.wijspread.HorizontalAlign.right); sheet.getCells(1,1,3,3).value("text"); sheet.getRows(1,3).height(60);
