Changes:
This release includes an enhancement for copying a cell over a range of cells. A new overload was added: AutoFitColumns (int firstRow, int firstColumn, int lastRow, int lastColumn, AutoFitterOptions options), making it possible to use auto-fitting options even in a range. Similarly, you may now copy tables when copying ranges. issues with rendering Excel files, rendering PivotTables and Pivot Charts, Excel to HTML, applying conditional formatting, rendering image files from worksheets, and exporting to PDF have been resolved. Issues pertaining to the formula calculation engine have also been fixed.
