I also encountered the same problem, that is, the query result data of futures margin. \x0d\ The data in each column cannot be added. If multiple data are selected, "Sum = * * * * * will not appear in the status bar. All re-entered data can be summed, but all pasted data cannot be summed. \x0d\ \x0d\ repeatedly looked for the reason, and found that there was an invisible "space" behind every column of data that I pasted, so I removed the "space": Edit-Replace-"space" was "empty". Note that "space" is the space bar input on the keyboard, and "empty" means nothing. "Spaces" can also be copied and pasted.
