I don't know. But I see that you have 5 extra rows and have a +5 in your formula!?

[Younsion]

yes...as you see,what i want is the piture 2,the each-loop include the '分组平均水平'(the extra 5 rows),so i do '+5' in the merge command...

Because of Corona, we are currently spending significantly less time on JXLS. Therefore an answer or processing can take longer.

You could upload an example template and a piece of source code. But please with no Chinese chars.

I just happened to encounter the same problem, which might be an issue. It could be that after merging the cells , the mergeCells command adjusts the Size, not using the default template cell Size. This leads to an increase in row or column index labels during subsequent loops, which results in new rows. You can customize a merge command that only performs the merge without changing the columns.

 @Override
  public Size applyAt(CellRef cellRef, Context context) {
    int rows = getVal(this.rows, context);
    int cols = getVal(this.cols, context);

    if (rows > 1 || cols > 1) {
      getTransformer().mergeCells(cellRef, rows, cols);
    }
    area.applyAt(cellRef, context);
    return area.applyAt(cellRef, context);
  }
