How to disable selection of cells in ag-grid?

Question

I have a simple ag-grid in an Angular project and want to disable selection of cells in one of its columns. Simply removing the default blue outline during selection would also be fine. I just want no visual change to the cell when the user clicks inside it. How can I do this?

I see that ColDef has a property suppressNavigable that sort of helps, since it disallows using the tab key to select the cells, but it still allows selection by clicking. Also, the grid itself seems to offer suppressCellSelection but it doesn't seem granular enough and doesn't seem to affect anything anyway.

So, how can I remove this blue border cell selection?

Here's the code I have for these column definitions:

this.columnDefs = [
  { headerName: 'One', field: 'one' },
  { headerName: 'Two', field: 'two' },
  { 
    // I want to disable selection of cells in this column
    headerName: 'I want no cell selection!', 
    field: 'three',   
    suppressNavigable: true,
    editable: false,
  }
];

Here's a stackblitz example I was using to test with.

Here's a screenshot of the blue border I don't want to see in this column:

Answer 1

Note that if we set gridOption.suppressCellSelection = true we can disable cell selection for all columns' cells.

Here the question is regarding not showing a specific column's cell's highlighted border when it is selected.

You can achieve this by bit of CSS and cellClass property of ColDef.

You'll need to add below CSS.

.ag-cell-focus,.ag-cell-no-focus{
  border:none !important;
}
/* This CSS is to not apply the border for the column having 'no-border' class */
.no-border.ag-cell:focus{
  border:none !important;
  outline: none;
}

And use the same class as cellClass in ColDef

suppressNavigable: true,
cellClass: 'no-border'

This won't show border for the cell you even focus using mouse click.
