Edited Unassigned: Column border quantum coupling [15562]

Downgrading to v. 4.0.3 fixed this issue for me.

Expected result:
- first two rows are bolded
- columns 8, 10, 12 and 14 have dotted right border

Actual result:
- all columns up to column 14 have dotted right border for the first two rows. There is some coupling between Row() and Column() accessors?

```
// TEST
var w = excel.Worksheets.Add("test");
w.Row(1).Style.Font.Bold = true;
w.Row(2).Style.Font.Bold = true;

for (var i = 0; i < 4; i++)
{
w.Column(8 + 2*i).Style.Border.Right.Style = ExcelBorderStyle.Dotted;
}
```
