Step 1: Besides the shared range, you need to hide the remaining areas that you don't want to show in the worksheet. In this scenario, I want to restrict the worksheet to just 4 columns and 10 rows. So I select the fifth column and then press the Ctrl + Shift + Rightward arrow keys simultaneously to select all right columns.

Step 2: Right click selected columns, and select the Hide from right-clicking menu.

Step 3: Select the first row below shared range, press the Ctrl + Shift + Downward arrow  keys at the same time to select all rows below shared range, and then hide them.

Step 4: Select the first row up shared range, press Ctrl + Shift + Up arrow simultaneously to select all rows up shared range, and then hide them.

Step 5: Select the first column left to shared range, press Ctrl + Shift + Leftward arrow  simultaneously to select all columns left to shared range, and then hide them.

Then you will see all rows and columns are hidden except shared range in the worksheet.

In Excel, users can set scrolling area to prevent from scrolling to other rows and columns.

Step 1: Right click the worksheet name in the Sheet tab bar, and then select the View Code from the right-clicking menu.

Step 2: Now you get into the Microsoft Visual Basic for Applications window, you need to open the Properties Window with clicking View > Properties Window.

Note: If the Properties window has been opened already, just skip this step.

Step 3: In the Properties window, find out the ScrollArea in the left bar, and then in the following box enter the range you want to share with others.

Step 4: Close the Microsoft Visual Basic for Applications window.

Then you will see both vertical scroll bar and horizontal scroll bar are freeze, and you cannot scroll to other rows and columns in current worksheet.
