Kingsoft Document Editor cannot display the phone number.

If your cell width is not enough, the numbers will be crowded together and not displayed, or displayed as pound symbols. Try to widen the cell width. If your phone number exceeds 1 1 digits, it will become a scientific notation in regular format, showing all numbers.

You can try changing the cell format to a numeric value, and you can enter the 15 string. Numbers can also be displayed in full. You can also click the right mouse button after selecting the column, select Set Cell Format, and select Custom 0 in Cell Format to restore the number to its original state.
