Column width bigger than expected

[Nicolás]

Hello, in this picture i have a table with columns F1, F2, F3, etc… They all have decimal type with min value 1 and max value 7, with one decimal. Why the size of column width is bigger than the space it requires? I have narrow option in the table view, and also I have tried save and verify data but it wont change that size, any ideas? Also, if i remove the column header in options, then the width is reduced like i expect it to be, but i need to have the column header visible…
