    Gilad's answer is great b/c it is compatible with Python 3. I modified it further to handle scenarios with a single column or row.

    # Format cell borders via a configurable RxC box
    def draw_frame_border(workbook, worksheet, first_row, first_col, rows_count, cols_count,thickness=1):
    
        if cols_count == 1 and rows_count == 1:
            # whole cell
            worksheet.conditional_format(first_row, first_col,
                                         first_row, first_col,
                                         {'type': 'formula', 'criteria': 'True',
                                         'format': workbook.add_format({'top': thickness, 'bottom':thickness,
                                                                        'left': thickness,'right':thickness})})    
        elif rows_count == 1:
            # left cap
            worksheet.conditional_format(first_row, first_col,
                                     first_row, first_col,
                                     {'type': 'formula', 'criteria': 'True',

            # top and bottom sides
            worksheet.conditional_format(first_row, first_col + 1,
                                     first_row, first_col + cols_count - 2,

    The current solution by @aubaub draws an empty box. I needed to draw a frame around existing values without overriding them. This is my function in case it helps anyone:

    def draw_frame_border(workbook, worksheet, first_row, first_col, rows_count, cols_count):
    
        # top left corner
        worksheet.conditional_format(first_row, first_col,
                                     first_row, first_col,
                                     {'type': 'formula', 'criteria': 'True',
                                      'format': workbook.add_format({'top': 1, 'left': 1})})
        # top right corner
        worksheet.conditional_format(first_row, first_col + cols_count - 1,
                                     first_row, first_col + cols_count - 1,
                                     {'type': 'formula', 'criteria': 'True',
                                      'format': workbook.add_format({'top': 1, 'right': 1})})
        # bottom left corner
        worksheet.conditional_format(first_row + rows_count - 1, first_col,
                                     first_row + rows_count - 1, first_col,
                                     {'type': 'formula', 'criteria': 'True',
                                      'format': workbook.add_format({'bottom': 1, 'left': 1})})
        # bottom right corner
        worksheet.conditional_format(first_row + rows_count - 1, first_col + cols_count - 1,
                                     first_row + rows_count - 1, first_col + cols_count - 1,

                                      'format': workbook.add_format({'bottom': 1, 'right': 1})})
    
        # top
        worksheet.conditional_format(first_row, first_col + 1,
                                     first_row, first_col + cols_count - 2,
                                     {'type': 'formula', 'criteria': 'True', 'format': workbook.add_format({'top': 1})})
        # left
        worksheet.conditional_format(first_row + 1,              first_col,
                                     first_row + rows_count - 2, first_col,
                                     {'type': 'formula', 'criteria': 'True', 'format': workbook.add_format({'left': 1})})
        # bottom
        worksheet.conditional_format(first_row + rows_count - 1, first_col + 1,
                                     first_row + rows_count - 1, first_col + cols_count - 2,
                                     {'type': 'formula', 'criteria': 'True', 'format': workbook.add_format({'bottom': 1})})
        # right
        worksheet.conditional_format(first_row + 1,              first_col + cols_count - 1,
                                     first_row + rows_count - 2, first_col + cols_count - 1,

    Currently there is no easy way to do that.

    XlsxWriter is an awesome module that made my old job 1,000x easier (thanks John!), but formatting cells with it can be time-consuming. I've got a couple helper functions I use to do stuff like this.

    First, you need to be able to create a new format by adding properties to an existing format:

    def add_to_format(existing_format, dict_of_properties, workbook):
        """Give a format you want to extend and a dict of the properties you want to
        extend it with, and you get them returned in a single format"""
        new_dict={}
        for key, value in existing_format.__dict__.iteritems():
            if (value != 0) and (value != {}) and (value != None):
                new_dict[key]=value
        del new_dict['escapes']
    
        return(workbook.add_format(dict(new_dict.items() + dict_of_properties.items())))
    

    Now build off of that function with:

    def box(workbook, sheet_name, row_start, col_start, row_stop, col_stop):
        """Makes an RxC box. Use integers, not the 'A1' format"""
    
        rows = row_stop - row_start + 1
        cols = col_stop - col_start + 1
    
        for x in xrange((rows) * (cols)): # Total number of cells in the rectangle
    
            box_form = workbook.add_format()   # The format resets each loop
            row = row_start + (x // cols)
            column = col_start + (x % cols)
    
            if x < (cols):                     # If it's on the top row
                box_form = add_to_format(box_form, {'top':1}, workbook)
            if x >= ((rows * cols) - cols):    # If it's on the bottom row
                box_form = add_to_format(box_form, {'bottom':1}, workbook)
            if x % cols == 0:                  # If it's on the left column
                box_form = add_to_format(box_form, {'left':1}, workbook)
            if x % cols == (cols - 1):         # If it's on the right column
                box_form = add_to_format(box_form, {'right':1}, workbook)
    
            sheet_name.write(row, column, "", box_form)
