DataGrid Columns are not the same size

[dolivoselvira]

Hello everyone, I was working with the Radzen component, but I face some issues trying to make the columns the same size, it doesn't matter if I change the size of the container in which I have the DataGrid it keeps showing columns with different sizes.

Is there anything I am missing?

You need additional empty column at the end with variable width to make sure that the rest of the columns will keep their exact width. This is how HTML tables works.
