要在reportlab的表格中设置单元格自动换行,可以使用`Paragraph`模块中的`Paragraph`类来实现。具体步骤如下:
1. 导入`Paragraph`类和`getSampleStyleSheet`方法:
```[python](https://wenku.csdn.net/doc/6412b46ebe7fbd1778d3f92a?spm=1055.2569.3001.10083)
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib import colors
from reportlab.platypus import Paragraph
2. 创建样式表:
```python
styles = getSampleStyleSheet()
3. 定义表格单元格的样式:
```python
cell_style = styles['Normal']
cell_style.wordWrap = 'CJK'
`wordWrap`属性设置为`CJK`表示在中文字符处自动换行。
4. 创建单元格并使用`Paragraph`类进行包装:
```python
p = Paragraph('这里是需要自动换行的文本。', cell_style)
cell = (p, )
`Paragraph`类的第一个参数为需要自动换行的文本,第二个参数为样式表中定义的单元格样式。
完整代码示例:
```python
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib import colors
from reportlab.platypus import Paragraph
from reportlab.platypus import [simple](https://wenku.csdn.net/doc/6412b6f6be7fbd1778d48997?spm=1055.2569.3001.10083)DocTemplate
from reportlab.platypus import [table](https://wenku.csdn.net/doc/5th6zsbvjq?spm=1055.2569.3001.10083)
def [create](https://wenku.csdn.net/doc/6412b66fbe7fbd1778d46b60?spm=1055.2569.3001.10083)_table():
styles = getSampleStyleSheet()
cell_style = styles['Normal']
cell_style.wordWrap = 'CJK'
data = [['这里是需要自动换行的文本。' * 5] * 2] * 5
table = Table(data, colWidths=100, rowHeights=50)
table.setStyle(
[('BACKGROUND', (0, 0), (-1, -1), colors.white),
('TEXTCOLOR', (0, 0), (-1, -1), colors.black),
('FONTSIZE', (0, 0), (-1, -1), 12),
('INNERGRID', (0, 0), (-1, -1), 0.25, colors.black),
('BOX', (0, 0), (-1, -1), 0.25, colors.black)])
# 包装单元格
for i in range(len(data)):
for j in range(len(data[i])):
p = Paragraph(data[i][j], cell_style)
table._argW[i][j] = p.wrap(table._argW[i][j], table._argH[i])
table._cellvalues[i][j].text = p
return table
if __name__ == '__main__':
doc = SimpleDocTemplate('example.pdf')
[element](https://wenku.csdn.net/doc/z7c28mgs2i?spm=1055.2569.3001.10083)s = []
table = create_table()
elements.append(table)
doc.build(elements)
这里的示例代码创建了一个包含自动换行的文本的表格,并将其保存为PDF文件。
