I'm facing an issue when opening a excel file with hundreds/thousands of rows of data, "Too Many Different Cell Formats"

So I'm trying to format a column not a cell. The only way I can figure out how to format a column is by formating each individual cell; by implementing the code listed below. I would like to format a column instead of a row. I have hundreds/thousands of rows of data to format. Any suggestions would be very much appreciated.

Thanks,

HSSFCellStyle cellStyle = wb.createCellStyle();
HSSFDataFormat dataFormat = wb.createDataFormat();
cellStyle.setDataFormat(dataFormat.getFormat("0.00"));

HSSFRow row = sheet.createRow(iRow);
HSSFCell cell = row.createCell((short)1);
cell.setCellStyle(cellStyle);
