How to prevent adding and removing columns in the spreadsheet component

[Doug]

I need to lock down the spreadsheet and prevent the user from adding or removing columns. I'd like to hide the highlighted items in the context menu below. How can I accomplish this?

Hello Doug,

The Spreadsheet does not have a parameter dedicated to disabling/enabling the context menu options you listed, but you can hide them with CSS: 

<style>
    .k-menu-item:has(.k-menu-link .k-svg-i-table-column-insert-left),
    .k-menu-item:has(.k-menu-link .k-svg-i-table-column-insert-right),
    .k-menu-item:has(.k-menu-link .k-svg-i-table-column-delete)
    {
        display: none;
    }
</style>

Here's an example that shows the effect of the CSS rule posted above: https://blazorrepl.telerik.com/wzaqQZwc20hdvW6f24
