Absolutely! python-docx fully supports targeting specific tables in a multi-table Word document and extracting/formatting their data to your requirements. Here's how you can make it work:

Can python-docx locate a specific table? #

Yes, you have several reliable methods to pinpoint the exact table you need:

• By index (simple but rigid): If you know the fixed position of your target table (e.g., it’s the 3rd table in the document), use zero-based indexing to access it directly:

  from docx import Document
  
  doc = Document("your_document.docx")
  target_table = doc.tables[2]  # Targets the 3rd table, since indexes start at 0
  

  Note: This works best if the document’s table order never changes.

• By content/keyword match (flexible): Most often, you’ll want to identify tables based on unique content like a specific header or key phrase. For example, if your target table has a header cell with "Project Metrics", loop through all tables to find it:

  from docx import Document
  
  doc = Document("your_document.docCriteria Calculate TangLAB function. WaitousABool 业_min柴？不对，重新写正确代码：
  doc = Document("your_document.docx")
  target_table = None
  
  for table in doc.tables:
      # Check the first header cell for your unique identifier
      header_text = table.cell(0, 0).text.strip()
      if header_text == "Project Metrics":  # Replace with your unique keyword
          target_table = table
          break
  
  if target_table:
      print("Found the target table!")
  else:
      print("Target table not found in the document.")
  

• By table style: If your target table uses a distinct built-in or custom style (e.g., "Accent 2" or "CustomReportTable"), filter tables by their style name:

  target_table = next((table for table in doc.tables if table.style.name == "CustomReportTable"), None)
  

Can python-docx fulfill your data extraction & formatting needs? #

Absolutely! Once you’ve located the target table, you can iterate through its rows and cells to extract data, then format it into your desired structure (like lists, dictionaries, CSV, etc.).

Here’s a practical example that extracts table data into a list of dictionaries (mapping headers to row values for easy processing):

if target_table:
    # Extract headers from the first row
    headers = [cell.text.strip() for cell in target_table.rows[0].cells]
    # Extract and structure row data
    extracted_data = []
    for row in target_table.rows[1:]:  # Skip the header row
        row_data = {}
        for idx, cell in enumerate(row.cells):
            row_data[headers[idx]] = cell.text.strip()
        extracted_data.append(row_data)
    
    # Use the extracted data as needed (e.g., save to CSV, analyze in pandas)
    print(extracted_data)

You can tweak this code to match your exact formatting needs—whether you need raw text, parsed values (like numbers or dates), or a specific output structure.
