  Hi,
  
  You can get the dirty cells collection by using the getDirtyCells method. You can filter the collection to get the dirty cells of a particular column.
  
  Please refer to the following sample that demonstrates the same:https://jscodemine.grapecity.com/share/m8FCj32oEkew_hVddNWYWA/

  HI,

  You may use the automerge method. Please refer to the following code snippet and let me know if you face any issues.

  
     var range = new GC.Spread.Sheets.Range(0, 0, 1, 2);/* select only single row */
      sheet.autoMerge(range, GC.Spread.Sheets.AutoMerge.AutoMergeDirection.column, GC.Spread.Sheets.AutoMerge.AutoMergeMode.restricted);
  
  

  You may also use the addSpan method on specified range. Please refer to the following code snippet.

  sheet.addSpan(0,0,1,2)
