//Add new Style to Workbook
Style style = workbook.createStyle();

//Setting the background color to Blue
style.setForegroundColor(Color.getBlue());

//setting Background Pattern
style.setPattern(BackgroundType.SOLID);

//New Style Flag
StyleFlag styleFlag = new StyleFlag();

//Set All Styles
styleFlag.setAll(true);

//Change the default width of first ten columns
for (int i = 0; i < 10; i++)
{
    worksheet.getCells().getColumns().get(i).setWidth(20);
}

//Get the Column with non default formatting
ColumnCollection columns = worksheet.getCells().getColumns();

for (Column column : (Iterable<Column>) columns)
{
    //Apply Style to first ten Columns
    column.applyStyle(style, styleFlag);
}
