public void setStyle(Style style)

Sets the style of this column.

This method only sets the given style as the default style for this column, without changing the style settings for existing cells in this column. To update style settings of existing cells to the specified style at the same time, please use applyStyle(com.aspose.cells.Style, com.aspose.cells.StyleFlag)

Parameters:

style - the style to be used as the default style for cells in this column.
