How can i render data from mysql table.
Handsontable is a client-browser-side JavaScript component. It does not offer anything in itself to connect to a server-side database. You have to write code to pull/push the data from/to the server.
Have a look at, say, http://stackoverflow.com/questions/30727318/handsontables-datas-to-sql-database. The principle there is to use AJAX to make HTTP calls to the server, which services the calls in a PHP script, which in turn accesses the database. https://github.com/handsontable/handsontable/blob/master/demo/php/save.php gives an example of PHP code servicing client calls.
Or, https://github.com/handsontable/handsontable/issues/686 seems to make the calls directly with the JSON dataType.
