可以设置cellsyle 的选项：

 
def _setCellStyle(cellStyles, i, j, op, values): 
    #new = CellStyle('<%d, %d>' % (i,j), cellStyles[i][j]) 
    #cellStyles[i][j] = new 
    ## modify in place!!! 
    new = cellStyles[i][j] 
    if op == 'FONT': 
        n = len(values) 
        new.fontname = values[0] 
        if n>1: 
            new.fontsize = values[1] 
            if n>2: 
                new.leading = values[2] 
            else: 
                new.leading = new.fontsize*1.2 
    elif op in ('FONTNAME', 'FACE'): 
        new.fontname = values[0] 
    elif op in ('SIZE', 'FONTSIZE'): 
        new.fontsize = values[0] 
    elif op == 'LEADING': 
        new.leading = values[0] 
    elif op == 'TEXTCOLOR': 
        new.color = colors.toColor(values[0], colors.Color(0,0,0)) 
    elif op in ('ALIGN', 'ALIGNMENT'): 
        new.alignment = values[0] 
    elif op == 'VALIGN': 
        new.valign = values[0] 
    elif op == 'LEFTPADDING': 
        new.leftPadding = values[0] 
    elif op == 'RIGHTPADDING': 
        new.rightPadding = values[0] 
    elif op == 'TOPPADDING': 
        new.topPadding = values[0] 
    elif op == 'BOTTOMPADDING': 
        new.bottomPadding = values[0] 
    elif op == 'HREF': 
        new.href = values[0] 
    elif op == 'DESTINATION': 
        new.destination = values[0]
