There are a few ways to display a set column range in Excel. One way is to use the "Format as Table" feature. To do this, select the range of cells you want to format as a table. Then, go to the "Insert" tab and click "Table". This will open a dialog box. In the dialog box, make sure that the "My table has headers" option is selected and then click "OK".
Once you have done this, your selected range will be formatted as a table. You can then go to the "Design" tab and use the "Table Style Options" group to choose which columns you want to be visible. For example, you can choose to only display the first column and last column by selecting the "First Column" and "Last Column" options.
Another way to display a set column range in Excel is to use the "Hide&;Unhide Columns&;Rows&;Cells&;Sheets&;Windows&;Workbooks&;Macros&" feature. To do this, select the range of cells you want to hide. Then, go to the "Home" tab and click "Format>Hide &; Unhide>Hide Columns>"
This will hide your selected columns. You can then unhide them by going to the same location and selecting "Unhide Columns>"
