Hi Jimmy Huang, 
 
Thank you for contacting Syncfusion support. 
 
From the provided code snippet, you have called the super.handleTap() method for all the cell tap functions. You can achieve your requirement by passing the tap function to the super method only when the RowColumnIndex.columnIndex is 0. Please refer the following code snippet. 




class CustomSelectionManager extends RowSelectionManager { 
  @override 
  void handleTap(RowColumnIndex rowColumnIndex) { 
    if (rowColumnIndex.columnIndex == 0) { 
      super.handleTap(rowColumnIndex); 
    } 
  } 
} 
 
We have prepared a sample for your reference. Please find the sample from the following link.
