下面是Python xlwt工具使用详解的完整实例教程,并包含两个示例说明。
xlwt
是Python编程语言的一个库,用于读取和写入Excel文件。它可以用来创建新的Excel文件,也可以用来修改已有的文件。
下面是生成Excel表格栏位宽度自适应内容长度的方法:
首先,安装xlwt
库。使用pip
命令即可:pip install xlwt
然后,导入xlwt
库。
python
import xlwt
Workbook
对象。python
workbook = xlwt.Workbook()
python
sheet = workbook.add_sheet('Sheet1')
python
sheet.write(0, 0, 'First Column')
sheet.write(0, 1, 'Second Column')
sheet.write(1, 0, '1')
sheet.write(1, 1, '2')
sheet.write(2, 0, 'AAA')
sheet.write(2, 1, 'BBB')
python
for i in range(sheet.ncols):
col_width = 0
for j in range(sheet.nrows):
cell_len = len(str(sheet.cell_value(j, i)))
if cell_len > col_width:
col_width = cell_len
sheet.col(i).width = col_width * 256
python
workbook.save('example.xls')
这样,生成的Excel表格中每一列的宽度就可以自适应内容长度了。
```python
import xlwt
workbook = xlwt.Workbook()
sheet = workbook.add_sheet('Sheet1')
sheet.write(0, 0, 'First Column')
sheet.write(0, 1, 'Second Column')
sheet.write(1, 0, '1')
sheet.write(1, 1, '2')
sheet.write(2, 0, 'AAA')
sheet.write(2, 1, 'BBB')
for i in range(sheet.ncols):
col_width = 0
for j in range(sheet.nrows):
cell_len = len(str(sheet.cell_value(j, i)))
if cell_len > col_width:
col_width = cell_len
sheet.col(i).width = col_width * 256
workbook.save('example.xls')
```
```python
import xlwt
workbook = xlwt.Workbook()
sheet = workbook.add_sheet('Sheet1')
# 合并单元格
sheet.write_merge(0, 0, 0, 3, '合并单元格样例')
# 设置单元格边框线样式
borders = xlwt.Borders()
borders.left = xlwt.Borders.MEDIUM
borders.right = xlwt.Borders.MEDIUM
borders.top = xlwt.Borders.MEDIUM
borders.bottom = xlwt.Borders.MEDIUM
# 添加数据
for i in range(1, 6):
row = sheet.row(i)
for j in range(4):
if i == 1:
row.write(j, '标题%d' % (j + 1))
else:
row.write(j, '数据%d' % (j + 1))
# 设置单元格边框
style = xlwt.XFStyle()
style.borders = borders
row.set_style(style)
# 自适应栏位宽度
for i in range(sheet.ncols):
col_width = 0
for j in range(sheet.nrows):
cell_len = len(str(sheet.cell_value(j, i)))
if cell_len > col_width:
col_width = cell_len
sheet.col(i).width = col_width * 256
workbook.save('example.xls')
```
以上是一个简单的xlwt
应用的实例说明。通过学习以上方法,你可以灵活地使用xlwt
库来生成各种Excel文件。
