Python ReportLab-表上的Wordwrap是分裂单词而不是在空格上

Question

我使用Canvas在ReportLab中创建了PDF：

self.pdf = canvas.Canvas(f'{file_name}.pdf', pagesize=A4)

我在表中创建表格以创建文档，但我的一张表并未按照我的期望包装。它不是在空间上闯入线路，而是在单词之间进行，如下所示。

下面的代码是我用于创建表的代码。只要我确保要传递到表（）的单元格是段落（）的时间。

def _discount_table(self, width_list):
    # Table Name
    table_name = Paragraph('DISCOUNTS', self.header_style_grey)

    # Create Header
    header = [Paragraph('NAME', self.table_header_style_left)]
    header += [Paragraph(x, self.table_header_style_right) for x in self.unique_discount_list]
    header += [Paragraph('TOTAL', self.table_header_style_right)]

    # Process Data
    discount_data = [[Paragraph(cell, self.table_style2) for cell in row] for row in self.discount_data]
    data = [[child_row[0]] + disc for child_row, disc in zip(self.fees_data, discount_data)]

    # Create Footer
    table_footer = [Paragraph('') for _ in range(len(header) - 2)]
    table_footer += [Paragraph('TOTAL', self.table_header_style_right),
                     Paragraph(f'{self.discount_total:,.2f}', self.table_header_style_right)]

    # Create Table
    bg_color = self.header_style_grey.textColor
    table = Table([header] + data + [table_footer], colWidths=width_list)
    table.setStyle([
        ('GRID', (0, 0), (-1, -1), 1, 'black'),
        ('BACKGROUND', (0, 0), (-1, 0), bg_color),
        ('TEXTCOLOR', (0, 0), (-1, 0), 'white'),
        ('BACKGROUND', (-2, -1), (-1, -1), bg_color),
        ('TEXTCOLOR', (-2, -1), (-1, -1), 'white'),
        ('FONTNAME', (-2, -1), (-1, -1), 'Helvetica-Bold'),
        ('FONTNAME', (0, 0), (-1, 0), 'Helvetica-Bold'),
        ('ALIGN', (1, 0), (-1, -1), 'RIGHT'),
        ('ROWBACKGROUNDS', (0, 1), (-1, -2), ['lightgrey', 'white']),
    ])

    return [table_name, table]

（请注意，Child_row [0]已经是段落 - 这是在上面的第12行中找到的）

我使用的造型是从另一个Python文件导入的：

    self.table_style2 = ParagraphStyle('table_style')
    self.table_style2.wordWrap = 'CJK'
    self.table_style2.alignment = TA_RIGHT

    self.table_style = ParagraphStyle('table_style')
    self.table_style.wordWrap = 'CJK'

    self.table_header_style_right = ParagraphStyle('table_header_style', self.table_style)
    self.table_header_style_right.textColor = colors.HexColor('#FFFFFF')
    self.table_header_style_right.fontName = 'Helvetica-Bold'
    self.table_header_style_right.alignment = TA_RIGHT
    self.table_header_style_right.wordWrap = 'CJK'

    self.table_header_style_left = ParagraphStyle('table_header_style', self.table_style)
    self.table_header_style_left.textColor = colors.HexColor('#FFFFFF')
    self.table_header_style_left.fontName = 'Helvetica-Bold'
    self.table_header_style_left.wordWrap = 'CJK'

因此，我真的丢失了，需要帮助。为什么表不正确包裹？

Answer 1

当我删除代码的WordWrap ='cjk'部分时，我能够修复表包裹问题。我在视频中看到了段落（）将自动wordwrap，所以我猜这两个元素如何重叠存在一些问题

self.table_style2 = ParagraphStyle('table_style')
# self.table_style2.wordWrap = 'CJK'
self.table_style2.alignment = TA_RIGHT

self.table_style = ParagraphStyle('table_style')
# self.table_style.wordWrap = 'CJK'

self.table_header_style_right = ParagraphStyle('table_header_style', self.table_style)
self.table_header_style_right.textColor = colors.HexColor('#FFFFFF')
self.table_header_style_right.fontName = 'Helvetica-Bold'
self.table_header_style_right.alignment = TA_RIGHT
# self.table_header_style_right.wordWrap = 'CJK'

self.table_header_style_left = ParagraphStyle('table_header_style', self.table_style)
self.table_header_style_left.textColor = colors.HexColor('#FFFFFF')
self.table_header_style_left.fontName = 'Helvetica-Bold'
# self.table_header_style_left.wordWrap = 'CJK'
