Why isn't there a phone number for the screen shot printed information?

First, open the Excel program on the computer, then open the form file, and select the cell that needs to display the mobile phone number.

Second, click "Data" in the menu above the main interface of Excel, then find "Data Validity" and click Open.

3. Then, in the data validity menu window, click the Settings menu.

4. Then, find "Text Length" in the drop-down menu in the "Allow" position and click to select it.

5. Then, find "Equal to" in the "Data" drop-down menu, and click to select it.

6. Then, find "1 1" in the drop-down menu at the location of "Length" and click to select it. Click "OK" to save.

Seven, after the completion of the setting, the phone number can be displayed normally on the mobile phone, and the problem is solved.
