java - Auto size height for rows in Apache POI / Libre Office issue -

-

i creating spreadsheet using apache poi. cells have newlines, , want height of cells fits height of content.

i using following code :

    public static void main(string[] args) throws ioexception {     hssfworkbook workbook=new hssfworkbook();     hssfsheet sheet =  workbook.createsheet("amap");        // sheet.autosizecolumn(0);      hssfcellstyle style = workbook.createcellstyle();     style.setwraptext(true);      addrow(sheet,style, (short) 0);      addrow(sheet,style, (short) 1);      addrow(sheet,style, (short) 2);         fileoutputstream fos = new fileoutputstream("test1.xls");     workbook.write(fos);     fos.flush();     fos.close();      system.out.println("ok !");  }  private static hssfrow addrow(hssfsheet sheet, hssfcellstyle style, short rownumber) {     //     hssfrow row =   sheet.createrow(rownumber);        // row.setrowstyle(style);     -- has no effect     // row.setheight((short)-1);   -- has no effect      hssfcell c = row.createcell(0);     c.setcellstyle(style);     c.setcellvalue("x");      c = row.createcell(1);     c.setcellstyle(style);     c.setcellvalue( "a\nb\nc");      c = row.createcell(2);     c.setcellstyle(style);     c.setcellvalue( "y");      return row;  }

when open generated file excel, working well.

but when open file open office, first line correct. height of second , third lines small

an idea ?

note : have tried add row.setrowstyle(style); , row.setheight((short)-1); seems have no effect
