Dear experts,
I would like to 'grayout' specific rows and merge columns for sap.ui.table.TreeTable. For example, for the table in the screenshot, I would like to 'grayout' the lines item 1 and item 2 and merge the cells of those lines, but the checkbox of those lines should be untouched.
Sample code could be found here.
Any help is appreciated it! Thanks.
Best regards,
Cheng
