ajax integration / datatable

I need to have ajax integrated with the "responsive" table displayed on '[login to view URL]' (i'll provide you the template). Also a "edit" column should be added as last column and a checkbox column (like on '[login to view URL]') should appear as first column. - on the "edit" column there will be "edit-delete" links, when clicked on the "edit" link then on the corresponding row values will appear in textbox so values can be edited (here is an example of script you can use '[login to view URL]', demo on '[login to view URL]') ; if clicked on the "delete" link then the row will disappear (see resource [login to view URL]) - a dropdown like on '[login to view URL]' should appear above the table to define the number of row to display - same pagination (1-2-...) as on '[login to view URL]' should appear at the bottom of the table - add a "delete selected" button above the table, so when clicked then row picked on the checkbox column will be removed - make appear a "add" button above the table, when clicked then on the page it'll appear a form with "code/company/price/change" row with textbox in front, so when submitted then a new row will appear on the table (see resources [login to view URL] ; [login to view URL]) - just create a simple mysql db with "code/company/price/change" fields, values will be inserted when submitted the "add" form (see point above) - note that the "responsive" table you have to use '[login to view URL]' render differently on mobile (resize the window to make it smaller you'll understand), so the "checkbox" column will appear as first row ; similar the "edit" column will appear as last row under the "Volume" row - other similar tasks will be needed later - no framework needed, core php is fine - don't hesitate if you've questions - you must have knowledge with php/mysql/ajax/javascript
