### Loading data from Excel file

Connector 1.0+ allows to use MsExcel file as datasource, you can load data from excel file in any component ( grid, chart, dataview, combo , scheduler )

To start using this feature you need to download libExcel - which is standalone project and not included in the connector's package You can grab it from here http://support.dhtmlx.com/x-files/connector/phpExcel.zip or from author's site http://www.codeplex.com/PHPExcel - unzip lib to the connector's folder.

Connector file will look as

    //files from ligExcel package
    require_once('lib/PHPExcel.php');
    require_once('lib/PHPExcel/IOFactory.php');

    //connectors
    require("../../codebase/db_excel.php");
    require("../../codebase/grid_connector.php");

    $grid = new GridConnector("../some.xls", "ExcelDBDataWrapper");
    $grid->render_table("A18:F83", "id", "A,B,C,D,E,F");

Constructor

- first parameter - name of excel file, absolute path or path related to the php file

render_table

- first parameter can be
  - range of cells in the spreadsheet, for example A18:F83
  - number of the top row, from which output need to be started, for example A4
  - “*” , which means include all not empty rows
- second parameter is the field , which will be used as id, you can use “id” for auto id generation
- third parameter list of columns, which will be used as columns in the grid

    $grid->render_table("A18:F83", "id", "A,B,C,D,E,F");

    $grid->render_table("A1", "id", "A,B,C,D,E,F");

    $grid->render_table("*", "id", "A,B,C,D,E,F");

If you want to load both data and header from excel file, it can be done by using GridConfiguration

    	$grid = new GridConnector($excel_file, "Excel");

    		$config=new GridConfiguration();
    		//array of cells, with labels for grid's header
    		$config->setHeader($grid->sql->excel_data(array("A3","B3","F13")));
    		$grid->set_config($config);

    	$grid->render_table("A18", "id", "A,B,F");
