使用python-docx设置表格单元格右对齐时WD_TAB_ALIGNMENT不生效如何处理

问题原因 #

你用错了参数，WD_TAB_ALIGNMENT是制表位专属的对齐参数，不适用单元格文本对齐场景。单元格内文本对齐需要调整段落的对齐属性，对应参数为WD_PARAGRAPH_ALIGNMENT。

调整步骤 #

1. 先导入所需的对齐常量
2. 给需要右对齐的单元格段落设置alignment属性为WD_PARAGRAPH_ALIGNMENT.RIGHT即可

修改后完整代码 #

# 新增导入对齐常量
from docx.enum.text import WD_PARAGRAPH_ALIGNMENT
from docx.shared import Inches

# 原有列宽设置不变
table.columns[0].width = Inches(14.0)
table.columns[1].width = Inches(2.0)
table.columns[2].width = Inches(2.0)
table.columns[3].width = Inches(3.0)

hdr_cells = table.rows[0].cells
hdr_cells[0].paragraphs[0].add_run("article")
# 表头后三列设置右对齐
hdr_cells[1].paragraphs[0].add_run("count")
hdr_cells[1].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT
hdr_cells[2].paragraphs[0].add_run("price")
hdr_cells[2].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT
hdr_cells[3].paragraphs[0].add_run("total")
hdr_cells[3].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT

for i in range (0, len(records)):
    row_cells = table.add_row().cells
    row_cells[0].paragraphs[0].add_run(records[i][0])
    # 数量、价格、总价列设置右对齐
    row_cells[1].paragraphs[0].add_run(records[i][1])
    row_cells[1].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT
    row_cells[2].paragraphs[0].add_run(records[i][2])
    row_cells[2].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT
    row_cells[3].paragraphs[0].add_run(records[i][3])
    row_cells[3].paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT

可选优化（减少重复代码） #

可以封装一个辅助函数简化对齐设置：

def set_cell_right_align(cell, content):
    cell.paragraphs[0].add_run(content)
    cell.paragraphs[0].alignment = WD_PARAGRAPH_ALIGNMENT.RIGHT

# 调用示例
set_cell_right_align(hdr_cells[1], "count")
set_cell_right_align(row_cells[1], records[i][1])
