As you can see i don't know how or why the last column from my ag-grid stays out while I use mat-tab-group,
I tried many things but nothing has worked. Any ideas are welcome :)
It's difficult to say exactly what the problem is without more information about your code and the specific behavior you're seeing. However, some potential issues could include:
.There may be a conflict between the CSS styles applied to the ag-grid and the mat-tab-group. This could cause one or the other to not display properly .The ag-grid or mat-tab-group may be improperly configured. Double-checking the configuration options and ensuring they are set up correctly could help .There could be a problem with the layout of your HTML. Make sure that the ag-grid and mat-tab-group are properly nested within their parent elements .There may be a problem with the data or data bindings being used in the grid. Verify that the data is being loaded correctly and that the bindings are set up correctly.
It is also helpful to include more details about your implementation such as version of Angular and Material, and any error message you encountered.
