FLEX DataGrid Column Modification - actionscript-3

Question

I am new in Flex. I want to display data in attached grid format. I found best way to display in DataGrid. But the CIs column has multiple entries so because of that other columns will duplicate. I want to avoid duplicate data in other columns. Attached screenshot is of excel, i want to achieve same format in Flex. I am using Flex 4.5

Answer 1

Best way I see to do what you want is to create a custom item renderer for the CLS column and have it render as a list control. That way, the CLS item in each row will only take up one row instead of multiple rows.

Answer 2

You can get some idea by following code... you can build logic using below concept for your implementation. Below example is sample not complete according to your requirement: -
