Documentation on cell alignment is incorrect

[joeohm]

When using the multiDataSet (from the styled_excel_sheet example), it seems that the styling for the vertical alignment does not follow the values that are outlined in the documentation:

alignment	vertical	"bottom" or "center" or "top"

I found the correct values to be "left", "center" and "right". Which also makes more sense.

Hope someone finds this info useful, or that you can update the documentation.
