Hi fei,

My apologies for the delayed response time.

If i understand, you are updating existing Manual Tables via uploading a CSV, right?

"There are eight columns of data, and two columns containing wdt _ ID are hidden."

Thank you for adding the screenshot, this part is clear.

1.Be assumed to have misaligned header names :

- We are not able to reproduce this.

Could you please record a Video, show us exactly which steps you do, which option you choose from the "Update existing Table" selection, do you just add new rows, i presume, or maybe choose from other two options, such as to replace the Data source, etc?

The best is to make a Video so that we can see what happens on your end.

If the Video gets too large for the ticket, you can use weTransfer and send us a download link.

2.be assumed not to have the same number of columns

- I am sorry, but i do not understand this part.

If you can elaborate and show us more details about that issue, too.

It is best if you can please open a new ticket for all the points besides #1.

When you have multiple questions or issues which are for different subjects/topics,

 please open a new ticket for each subject, and we will help/advise more effectively. 

In that way, issues and questions which are related to different subjects will be in separate tickets so other users or our support agents can find them easily. 

Our policy is to have one issue or question per ticket for the reasons described already.

Thank you for understanding.

3.Another way to paste Excellike is not possible for hidden columns

- Yes, our Excel-Like Editor has certain limitations at the moment.

Please click here to see the complete list of limitations when we compare the "Standard Editor" with Excel-Like Editor (we intend to remove those limitations in future versions).

If you have additional questions about pasting values for Excel-Like Editor, please also open an additional/separate ticket on that subject.

4.The willy-nilly inserted wdt _ ID column confuses

I apologise, but i did not understand what you mean by this.

If you can please open a new ticket and there elaborate in more details, add some screenshots;

The best will be if you can record a Video to show us exactly what you mean by that and we can advise.

5. I want to update hidden columns without affecting the frontend :

My sincere apology once again, but i am also not 100% sure what you mean by this.

If you can please open a separate ticket, it will get assigned to me, if you can elaborate a bit more details what happens in that scenario and we will advise what is possible at the moment.

Thank you.
