Is there a way to add rows or columns to the existing table

[DuskBelievers]

I want to add a new row to an existing table, is there a way to do that

[nikozhoufromchina]

@DuskBelievers I have encountered the same problem, and it seems that this feature is not currently encapsulated. But I can share an idea, which is to encapsulate a table processing object. After obtaining the table object, it is passed in to this table processing object. Two modules are set up in the table object. One is to record various parameters of the original table, such as coordinates, height, width, number of columns, and data in the table. Then, create a new table, add rows and columns, pass in various parameters, and output them to PPT. It is theoretically feasible. You can give it a try. If you have any questions, please feel free to communicate together

Thank you for your reply. I am doing the same at present, but it is a little troublesome. I hope that the official will encapsulate this function in the future. Thank you again, stranger!

@DuskBelievers I plan to encapsulate this functionality using ChatGPT and share it on the platform. lol, let's look forward to it together!

[DuskBelievers]

It's a good idea. I'm looking forward to it

Can you take a look at the fork https://github.com/AndreasSteiner/python-pptx

[nikozhoufromchina]

Can you take a look at the fork https://github.com/AndreasSteiner/python-pptx Thank you for sedrew's response. It turns out that this issue has already been resolved very well. I just tested it, and it works great. Once again, thank you sedrew!!!

[DuskBelievers]

I also noticed the "add" method before, but I kept getting errors when I tested it.

[nikozhoufromchina]

As sedrew mentioned earlier, please use "pip install python-pptx-valutico" to install it. After installation, you should no longer encounter any errors. You can give it a try.

[DuskBelievers]

That's true. That problem is solved. I really appreciate your help.

@Dasc3er thanks，guys

[astafan8]

Hi! Are there any news on this feature? Does this ability exist in the python-pptx original package and using public API (without using attrbiutes and methods that start with underscores)?

[DuskBelievers]

@astafan8 first,pip install python-pptx-valutico and then

[astafan8]

thank you ! and is python-pptx-valutico a package that will be kept alive by it's authors and will used instead of python-pptx by all?

[DuskBelievers]

i think so, https://pypi.org/project/python-pptx-valutico/
