PDFplumber提取表格时遗漏最右侧列的问题求助

在Windows 11系统下使用pdfplumber提取表格数据时，多数场景效果良好，但针对特定PDF文件，extract_table方法会遗漏表格的最右侧列，不过page.search方法能够定位到该列的内容。以下是测试代码、运行输出及相关信息，恳请提供解决线索。

测试代码 #

# pdftesting.py
import pdfplumber
import sys

print('pdfplumber version:', pdfplumber.__version__)
print('Python version:', sys.version)
filepath  = 'C:/ProgramData/PythonProgs/testing/testdoc.pdf'
fn = pdfplumber.open(filepath)
page = fn.pages[0]

vlines = [26.0, 106.25, 152.25, 251.25, 395.5, 467.25, 539.5, 624.65, 692.5, \
          760.15, 818.9811199999999]
imagefile = 'C:/ProgramData/PythonProgs/testing/testdoc.png'
im = page.to_image(resolution=300)
im.draw_vlines(vlines, stroke_width=3)
im.save(imagefile)
lines = page.extract_table(table_settings=\
       {"vertical_strategy":"explicit",\
        "explicit_vertical_lines":vlines,\
        "horizontal_strategy": 'text',\
        "snap_tolerance": 5})
for item in lines:
    print('line:', item)
    
print('page width:', page.width)
target = 'inc'
X0 = page.search(target)[0]['x0']
X1 = page.search(target)[0]['x1']
size = page.search(target)[0]['chars'][0]['size']
print('Found:', target, X0, X1, size)
