Select all the column NOT to be protected;
Use Format | Cells | protection and deselect the Lock box
Now Tools | Protect | worksheet

In addition to above, also tick the box for hidden and format the cell with font same colour as background.

This will then be hidden in the formula bar and not visible on the sheet. However users would be able to copy the cell elsewhere and then see the contents. Unless, you deselect the option for selecting locked cells in the list when in the Protect sheet window.

Apologies, I may have confused the situation!!

Select the whole sheet and use Cell format window > Protection tab to remove the Locked tick and Hidden tick, so both check boxes blank.

Then Select the column to be protected and use the Cell format window > Protection tab to tick the locked and hidden check boxes.

Format this column with same colour font as background if you want it invisible.

Then Tools > Protection > protect Worksheet. In the list of options available, deselect the Select Locked cells option.

However, one slight flaw to this method.

The user won't be able to select the locked cells or the whole sheet but if he were to use the mouse to highlight an area which included the locked column, the contents would show in inverse colour, eg white on black rather than black on white.

Thanks

You can hide the column and then protect the sheet.

If you would like the the values to be visible,I suggest you follow the advice mentioned above by Rob Henson without changing the font colour.
