要在Reportlab中垂直对齐表格中的段落,可以使用以下方法:
textTransform
属性: 在创建Paragraph对象时,可以设置textTransform
属性为Paragraph.TB_CENTER
,这将使段落在表格单元格中垂直居中对齐。
示例代码:
from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib.units import inch
from reportlab.platypus import Paragraph, Table
from reportlab.pdfgen import canvas
c = canvas.Canvas("test.pdf", pagesize=letter)
styles = getSampleStyleSheet()
text = "这是一个测试段落。"
p = Paragraph(text, styles"Normal")
data = ["A", "B",
["C", "D"],
["E", "F"]]
table = Table(data, colWidths=2 inch, 2 inch)
table.addCell(p)
table.wrapOn(c, 0, 0)
table.drawOn(c, 0, 0)
c.save()
textAnchor
属性: 在创建Paragraph对象时,可以设置textAnchor
属性为Paragraph.TA_CENTER
,这将使段落在表格单元格中水平居中对齐,同时可以设置textTransform
属性为Paragraph.TB_CENTER
,这将使段落在表格单元格中垂直居中对齐。
示例代码:
from reportlab.lib.pagesizes import letter
from reportlab.lib.styles import getSampleStyleSheet
from reportlab.lib.units import inch
from reportlab.platypus import Paragraph, Table
from reportlab.pdfgen import canvas
c = canvas.Canvas("test.pdf", pagesize=letter)
styles = getSampleStyleSheet()
text = "这是一个测试段落。"
p = Paragraph(text, styles"Normal", textAnchor="center", textTransform="TB_CENTER")
data = ["A", "B",
["C", "D"],
["E", "F"]]
table = Table(data, colWidths=2 inch, 2 inch)
table.addCell(p)
table.wrapOn(c, 0, 0)
table.drawOn(c, 0, 0)
c.save()
这样,在Reportlab中创建的表格中,段落将垂直居中对齐。
