The support replied they can't do anything about that because we are using a third party plugin for tables. So hopefully the plugin developers will fix that in the future. Anyway, now the copy-pasting of rows has improved a lot, so instead of using CTRL you can just select a row and you can past it into a new row without loosing the format or getting the table distorted.
Example:
1
Colombia
05:00
05:00
2
Great Britain
05:12
10:12
3
Tunisia
05:24
11:24
4
Croatia
05:36
11:36
Adding a row, selecting Colombia row and copying it into the new row:
1
Colombia
05:00
05:00
2
Great Britain
05:12
10:12
3
Tunisia
05:24
11:24
4
Croatia
05:36
11:36
1
Colombia
05:00
05:00
Adding a column, selecting a whole set of columns and copying it into the new column:
1
Colombia
05:00
05:00
05:00
2
Great Britain
05:12
10:12
05:12
3
Tunisia
05:24
11:24
05:24
4
Croatia
05:36
11:36
05:36
You can now also change the column size by a symbol which appear if you pass near the separation line with your mouse.
