xlsxwriter / 如何用空格（''）填充所有空白单元格？

Question

So, I want to do this for styling: to prevent text overspilling, without doing a text wrap.

I'm not sure even where to start with this one. I know there's a {'type':'blank'} attribute you can use... but I'm not sure what to do with it.

My code so far is below.

def export_to_xlsx(date):
    global df
    ## CREATE PD DATAFRAME
    all_mp_dict = scraper(date)
    df = pd.DataFrame(all_mp_dict)

    ## WORKSHEET FORMATTING
    workbook_loc = './mp_excel/mp_data_'+date+'.xlsx'
    writer = pd.ExcelWriter(workbook_loc, engine='xlsxwriter')
    df.to_excel(writer, sheet_name=date+'_raw')

    workbook = writer.book
    worksheet = writer.sheets[date+'_raw']

    header_format = workbook.add_format({
        'bold': True,
        'text_wrap': True,
        'valign': 'top',
        'fg_color': '#FFFF00',
        'border': 1})

    for col_num, value in enumerate(df.columns.values):
        worksheet.write(0, col_num+1, value, header_format)

    ## TO_EXCEL
    writer.close()
