Adding custom icon on table header beside Search icon

I have seen an issue has already been raised to check if any additional icons can be added along with other icons in the table header.
But I want to add an icon at the beginning of the table header icons

## Expected Behavior
Need to know if I can add a new icon beside the Search Icon i.e. MyIcon should be the first icon and then followed by Search, Filter, Columns etc.

## Current Behavior
I have seen an issue has been raised to add icon, but when I try to add it. The icon is added only to the extreme right.
