Applying alignment style for SpredSheetML in .NET

Hi

I observe different approach in applying alignment style settings between Aspos.Cells and Excel.

In example SpreadSheetML I got set two styles one default with alignment vertical and horizontal set and one custom with set only vertical alignment.

<Styles>  
  <Style ss:ID="Default" ss:Name="Normal">  
    <Alignment ss:Vertical="Bottom" ss:Horizontal="Left"/>  
    <Borders/>  
    <Font ss:FontName="Calibri" x:Family="Swiss" ss:Size="11" ss:Color="#000000"/>  
    <Interior/>  
    <NumberFormat/>  
    <Protection/>  
  </Style>  
  <Style ss:ID="TestAlignment">
    <Alignment ss:Vertical="Top" ss:ReadingOrder="LeftToRight" />
    <Borders />
    <Font ss:FontName="Calibri" x:Family="Swiss" ss:Size="11" ss:Color="#000000"/>
    <Interior />
  </Style>
</Styles> 

and got two rows first will use default style second custom

<Row>  
  <Cell><Data ss:Type="Number">1</Data></Cell>  
  <Cell><Data ss:Type="Number">2</Data></Cell>  
</Row>  
<Row>  
  <Cell ss:StyleID="TestAlignment">
    <Data ss:Type="String">Test</Data>
  </Cell>  
  <Cell ss:StyleID="TestAlignment">
    <Data ss:Type="Number">2</Data>
  </Cell>  
</Row>

When we compare directly open spreadsheetML in Excel with xlsx file created using Aspose.Cell base on the same spreadsheetML we see that alignment is set differently. Cells A1 and B2 in example here spreadsheetML was open directly in Excel have set only Vertical = Top alignment as it is set TestAlignment style and Horizontal was set to default value (General). On file from Aspose.Cells situation is different the same calls have got Vertical = Top and Horizontal = Left. So it looks like Excel approach is to use settings only from style assign for current cell ignoring Default style settings. Aspose.Cells approach is to merge style settings, we got Vertical setting from cell style TestAlignment and Horizontal setting from Default style.

This can be observe on attached screenshot

Aspose.Cells approach seems to be in good approach because general style got update values from more details styles but because in Excel it works different (not necessary fine) I think that this should be change to way as Excel is handling it.
