DataGrid - The grid's layout is broken after adding columns and group summaries dynamically

created 6 years ago

We have found an issue when using the group totals together with the dynamic column list modification.

We let out users show group totals on demand, its turned on dynamically by js
We also let them modify the list of the columns dynamically

None of the two operation is very sophisticated or cause issues.

At the same time when the two are used at the same time, the layout gets broken .

To reproduce the issue, please use the following code pen:
https://codepen.io/mikus/pen/yZLjqq

Start with adding the columns (1. add column) -> see that the columns have been added to the end of the grid
Now press the '2. show group totals' button -> the group headings have been added, but the column bands have been lost and the general layout gets messy (depending on the configuration).

if you perform any of the two actions separately, you;ll see that they both work.
Could you please let us know what causes the conflict? Is there any workaround?

Regards
