Phpmyadmin like inputs

I am trying to change some tables to dynamically changeable tables (click on the cell to modify the content - Essentially you click on the cell and it converts the content to a textbox to be modified when you click off it submits the data to a php statement to be saved). I am not very familiar with jquery or ajax so this is going to be difficult.

currently I am just trying to achieve the first part (click and convert to a textbox - click off and convert back to text)

I found this elsewhere on stackoverflow

so ideally I would want to delete the

   <td><button>Edit</button></td>

any help is appreciated.
