<div class="m__sub_content">

I would like to ask if my table data depends on tableData,. The current business logic is to change the style of I that the front end will download when you click to download.
how do you operate it? Usually I use scope.row to get the current line when there is data in the backend.
but there is no corresponding data value for this I here. How to change-sharp-sharp-sharp problem description separately
