In Excel 2011 for Mac, you can hide entire worksheets or just some columns or rows. And you can unhide them, too. This control over what can be seen or not can be helpful in hiding content such as:
Content that needs to be used in a formula, but need not be visible
Content that you link from, but you don’t need to show it to everyone
Just remember that you can also wind up having secrets that others know how to discover with these methods! Use these options to hide or unhide a complete worksheet:
To hide a worksheet: Choose Format→Sheet→Hide.
To unhide a worksheet: Choose Format→Sheet→Unhide.
You can also right-click any worksheet tab to bring up a menu that has a Hide option. Similarly, right-click any visible worksheet tab to bring up the same menu with an Unhide option.
If your workbook has just one unhidden worksheet, or even just one worksheet in the entire workbook, you won’t be able to hide it.
To hide a row or rows: Select a complete row or multiple rows. Then choose Format→Row→Hide. Or right-click the row header and choose the Hide option.
To hide a column or columns: Select a complete column or multiple columns. Then choose Format→Column→Hide. Or right-click the column header and choose the Hide option.
To unhide rows or columns: You must first select the surrounding rows or columns by using the dark arrow cursor in the row number or column heading before you can unhide by choosing Format→Row (or Column)→Unhide. You can also select surrounding rows or columns, right-click the row or column header, and choose the Unhide option in the resultant menu.
