Final answer:
To remove all borders from selected cells in a spreadsheet application like Microsoft Excel, use the command accessible from the Home tab in the ribbon, choose the Borders button, and select No Border.
Step-by-step explanation:
The question refers to the task of removing all borders from selected cells in a spreadsheet or other table-based application, which can be done using a single command. While this can depend on the specific program being used, in Microsoft Excel for example, you can achieve this by right-clicking the selected cells, choosing Format Cells, navigating to the Border tab, and then selecting None to remove all borders. For a quicker method, you could use the ribbon command by selecting the cells, going to the Home tab, finding the Borders button in the Font group, and choosing No Border from the dropdown menu.
