DataGrid Cells Merge and Columns Crud Features
Cells Merge - allows you to span a cell through multiple rows or columns. To use this feature, you need to access a Grid cell, through the Grid's 'rows' array. Each row in the 'rows' array has 'cells' array. It allows you to access a cell and set options of that cell like: 'rowSpan', 'colSpan', 'backgroundColor', 'color', 'value', 'fontSize', 'fontWeight' and 'fontFamily'.
