We have implemented a table with buttons for editing and deleting rows. When a row is selected and the edit button is clicked, the information from that row is passed to a Bootstrap modal window.
Upon clicking the edit button, the Bootstrap modal popup appears, displaying the values of the corresponding row inside it. When the submit button inside the modal popup is clicked, we want the edited values to be updated in the table row without needing to reload the webpage.
I have a table that is displaying information from tables and I have added a feature that after every row there is an edit button so that when the user clicked you can update the information for that row.I have created a popup using bootstrap that will show up when you click on the edit icon in the table row.
