当我在Apache POI库中使用Calibri字体时，在可运行jar中的列宽度未正确显示

Question

I have built a java application using apache poi. It is a simple swing gui app and it generates excel using apache poi library. After generating sheet I have set autofit column, which is working perfectly fine when I am running the application with RAD . Now I have generated runnable jar (which is my requirement) and it generates excel but all columns after second column are hiding behind one another .

I removed autosize column and columns didnt hide behind each other. But I want my columns to be autosized according to text. Please tell me what is the correct way to use autosize. And why its working in RAD and not in runnable jar.

I get this is font issue. I removed the line where I am setting font name and it worked good. Now my question is how can I use Calibri font. Please help.

Here is my code for writing excel:

public class Excel {
    HSSFWorkbook wb;
    HSSFFont head, defFont;

    public Excel() {
        wb = new HSSFWorkbook);
        //create header font to use Calibri and bold text
        //create default font to use Calibri and normal text
    }

    public void sheetGen() {
        HSSFSheet sheet = wb.creatSheet("sheet1");

        //create style
        //create each row and column
        for (int i = 1; i < 9; i++) {
            if (i != 2)
                sheet.autoSizeColumn(i);  //this is not working in runnable jar
        }
        //write workbook
    }
}

On some platforms, Calibri is a third party font; for example, it is included with Microsoft Office on Mac OS X. Instead, use the desired logical fonts from among the five font families defined by the Java platform. For example,

Header: new Font(Font.SansSerif, Font.BOLD | Font.ITALIC, 14)

Default: new Font(Font.Serif, Font.PLAIN, 12)
