How can I pass an input short text answer to a table line entry

Hello,

How can I pass an input sort text answer to a table line entry?

Imagine I have a question on my form that I request a user to input the name,and I want that name to appear on next question tables

Sorry, can you please specify what did you mean by "table line entry"?
You can easily pass short text entry value to another entry field using the "Update/Calculate Field" conditions Please refer to this article for more information.
How to Pass Field Value to Another Field?

Sorry, what I mean is:

In my Jotform I have a short input text field and the next question is a table question that the line description should be filled with the textbox input. There is a way to do that?

Thank you in advance.

I have checked your test form. You have explored the text field and fetched value via a unique name! This is very nice. I just want to make a little addition. You can use get value with a unique name in input table titles.Please contact us if you have any questions.

When you say is "not available here", means that I cannot put the unique name {seleccinouOutro} there and the form will assume the textbox input?

Yes, exactly. We can't transfer the value to this field with {seleccinouOutro}.

Ok, thank you for the clarification, there I a way to do that?

If I understand correctly, you wanted to prefill the Input table field textbox with data from Short Entry field(textbox). This is currently not possible within the Form Builder. 

Although you can extract the individual cell values of Input Table field, you cannot prefill them in reverse.

Let us know if this is not what your inquiry was about.
