注意,合并单元格并赋予合并后的单元格的样式时,必须将所合并的单元格“全部创建”!!!!否则单元格的格式会缺失!!!

excel转html预览时,单元格函数未进行计算,则需要加上如下代码,重新声明该单元格为函数
FormulaEvaluator evaluator = workbook.getCreationHelper().createFormulaEvaluator();
for (int i = 0; i < sheet.getPhysicalNumberOfRows(); i++) {
HSSFRow row = sheet.getRow(i);
for (int j = 0; j < row.getPhysicalNumberOfCells() ; j++) {
HSSFCell cell = row.getCell(j);
if(cell.getCellType()==CellType.FORMULA.getCode()){
evaluator.evaluateFormulaCell(cell);
}
}
}
sheet.setForceFormulaRecalculation(true);
