Multi Column Headers - Cell border issues when Grouping

[AGB]

Hi Guys,

Have just tripped over some display issues with multiple column headers when grouping is applied.

To demonstrate the problems please run the following dojo

        https://dojo.telerik.com/IgUxidOQ
        
and should see the grouped column header shows a border line as if it was are multi column header (see Header1.png).

Now if you lock the ContactName column the grouped column displays correctly but the CompanyName header column is missing a left hand border (see Header2.png).

Regards
Alan

Hi Alan,

I have examined the screenshots and the example and the behavior is indeed not expected. 

The extra border in the group header cell can be easily removed by adding the CSS below:

.k-grid-header th.k-group-cell {
    border-bottom: 0;
}

Regarding the other border - I am afraid that there is no straight-forward workaround that can be applied. Nevertheless, I have logged this and the other issue in our GitHub repository and you can monitor their status below:

• https://github.com/telerik/kendo-ui-core/issues/5179
• https://github.com/telerik/kendo-ui-core/issues/5180
  

I apologize for any inconvenience this behavior may cause you. As a token of gratitude for bringing it to our attention I have updated you Telerik points.

Hi Viktor,

Thank you for your investigations and confirmation my findings are issues within the current grid code.

Will now monitor the GitHub repository for further updates.
