You can do two things.

  1. Write the logic that changes this object into array or array of objects.
  2. If you have hard coded data then write it in this way countries : [ { country : 'US', id: 1, } ] Something like this

I think I will go with the first option. But will I be able to add the unique name and ID then

Yes you can further spread the object or array. Read about spread operator

After looking at your code it looks easy to me now 😀, I am trying to create table too, but I don't have table data, what I have is row no and column no and based on them I am tring to generate empty table for input, the problem which I am facing is creating header, do you have any suggestions for that ??, I really need some help

You mean let's say you want to generate 3×4 table?
I am not really sure but you can store rows and columns numbers into variable and based on that generate the table.

Hey im glad to start the discussion once again, I want to edit the row field may be by one time click on the row or having a separate button ,Can you explain to make it happen.

Abdul Basit

It depends on your approach. How do you want to edit? Do you have input fields for edit row data? I mean the same input fields which will be used to add and edit data, and the second approach is to convert the same row's td into input field

It's cool btw, but my case is to just edit the tr on a button click and update the state

Here you go... you just need to change renderTableData function with below code. Let me know if it helps...

   renderTableData() {
      return this.state.students.map((student, index) => {
         let col = Object.keys(student)
         return (
            <tr key={student.id}>
               {col.map((val, index) => {
                  return <td key={index}>{student[col[index]]}</td>
               })}
            </tr>
         )
      })
   }

Hi Abdul Basit, this is very helpful to me. Thank you!

How can I add rows to table dynamically? For example, if I create a table for a customer that have unknown number phone devices. So if a customer have 2 phone devices, we should have 2 rows, and if 3 phone devices, we should have 3 rows, etc.

Would you be able to show us how to add rows to a table?

Thanks
Ahmed

The key is supposed to be consistent between renders, random generated is a very bad solution.
Better use the array index if you don't have an unique identifier.

For that we will use another function called addData that will be called on clicking submit button, and we will add input data to our object using spread operator.
