How to insert, delete rows and blank rows in PDF tables

PDF does not save the table structure, and adding, deleting, and blank lines cannot be directly manipulated like in spreadsheet software. This article explains which changes can be made directly in the PDF, which ones need to be exported first and then transferred back, and how to check after the changes are made.

Key points of this article

  • PDF does not save the table structure, and only changing a certain text can be done directly in the PDF editor.
  • To add or delete entire rows or delete blank rows, you usually need to export it to Excel or Word first, and then convert it back to PDF after making the changes.
  • It is recommended to add a new table in Word or Excel first, and then use page operations to insert it into the target page.
  • The scanned PDF table is an image, which needs to be recognized into text using OCR first, and the recognition results must be compared with the original item by item.
  • After making changes, check the number of rows and columns, totals, table lines and page spreads, and save the changes as a new file.

When processing tables in PDF, there are three common needs: the table is missing a row and needs to be added, a certain row is redundant and needs to be deleted, or you want to add a new table at a certain location. But PDF records where each character is drawn on the page, and does not save the row and column structure of the table. Therefore, many people cannot find the entrance to add or delete lines in ordinary browsers, and manually moving text and lines can easily make the changes more confusing.

This article is written for readers who need to modify contracts, quotations, experimental data sheets, or paper appendices. After reading, you can judge which modifications can be completed directly in the PDF, which ones need to be exported first and then modified, and know how to check after the modifications are completed.

The following method takes the PDF editor of the OmniDoc desktop client as an example, but the general idea is also applicable to other tools.

How to add, delete rows, and insert new tables into PDF tables? One sentence conclusion

Directly modifying cell text saves trouble; if you want to add or delete entire rows or delete blank rows, you usually need to export the table to Word or Excel first, and then export it back to PDF after making the changes; when you need a new table, it is recommended to prepare it in the document software and then insert it.

Before you start: Confirm these points first

Spending two minutes to judge before taking action can save you a lot of detours.

  • Whether the document is a digital version or a scanned version. Use the mouse to try to select a word in the table: if you can highlight it, it means it is a digital version; if you can only select the entire picture, it means it is a scanned copy, and you need to do OCR first.
  • Whether the table structure is complex. Merged cells, slash headers, and nested tables are easily misaligned after export. Before making any changes, read the original table carefully and note which areas require manual review.
  • Whether there are dependencies. If the total rows, subtotals and percentages are calculated by hand, the values will become invalid after adding or subtracting rows and need to be recalculated. If it is a formula in spreadsheet software, check whether the formula reference is still correct after exporting.
  • Whether to keep the original. For documents such as contracts and quotations, all modifications should be saved as new documents, and the originals should be retained for comparison.
  • Whether the font will change. When exporting and then converting back to PDF, Chinese fonts and special symbols may be replaced, and the display effect needs to be checked after completion.

Steps to export a table in OmniDoc, add or delete rows, and then convert back to PDF

If you only change the text in a certain box, there is no need to export: modify the paragraph text directly in the PDF editor and check the alignment after making the changes. When you need to add or delete rows, follow the steps below.

  1. Download and open the OmniDoc desktop client at download.omnidoc.top, and use the PDF editor to load the file to be modified.
  2. If the form is a scanned copy, first use the OCR function to make the text in the form selectable, and check the recognition results before continuing.
  3. Export the page containing the target table to Excel or Word. Data-intensive tables are suitable for exporting to Excel, and contracts or report tables with more text descriptions are suitable for exporting to Word.
  4. Add or delete lines in the exported file. When deleting blank rows, delete blank rows in Excel and delete empty paragraphs in Word.
  5. Save the modified file, and then use the "Export to PDF" function of your document software to generate a new PDF.
  6. Use the page operation of the PDF editor to insert the new page into the corresponding position of the original file. If you only want to replace a few pages, use the split function to cut the original file, and then use the merge function to put the new pages back together.
  7. Save as a new file and proceed to the verification steps below.
