i want to automatically colspan as value


as you can see, i make grid like b.jpg(before) and i want to change to a.jpg(after) when i show it.

I try to setColspan or Grouping in first time. however, it is very inefficient because of a lot of data.

I heard that other program provide programmer with automatically merge API by same value.

So, i search this API in dhtmlx but i cannot find it.

pleas give me how can i solve it.

Sorry, but dhtmlxGrid doesn’t support such kind of API as “merge by value”
