Hello,

I have a table where each column heading is a year. The numbers in the
table display 5 places after the decimal point. When I select all and format
the cells as a Number with only 3 decimal places, the years in the column
headings are also displayed with the three decimal places, like this:

1990.000 1991.000
13.478 13.902

How can I only format the numbers that already have places after the decimal
point - i.e.
Before
1990 <- doesn't have decimal places
13.47895 <- has places after the decimal point

Thanks you!
