How to add new columns based on new input from users which is stored in a list

Tags: #<Tag:0x00007efc6232be68> #<Tag:0x00007efc6232bc38>

my appended list from user [[‘Folder1’, ‘2’], [‘Folder2’, ‘1’], [‘Folder3’, ‘3’]]

This is my expected output :

Likewiser under folder1 => 2 elements needs to be created, under folder2 => 1 elements needs to be created and under folder3 => 3 elements needs to be created

it should be based on the input values from the list…
can you give me some reference to do this

Hi @rameshpandiram

And how do you keep data for those Folders?

Let me give you something to start with https://jsfiddle.net/u3n5z4c2/

This is the current structure of the table.

We have set custom row headers with a className that aligns the titles to left and a parameter that changes the width of those headers to 200 pixels.

We set up custom nestedHeaders with 2-levels.

Data is filled from an array of objects with corresponding columns settings.

Please tell me if that is close to what you would like to achieve?

I haven’t asked like this anway Thanks for your kind reply I solved it… That is from user input which is collected in list that need to genrate a new column based on the given input respectively

Do you need any further help or should we close this thread?
