Show or hide column base on condition

[snv]

To hide grid columns using custom script, you can call this function at your desired event:

function removeColumns(frm, fields, table) {
    let grid = frm.get_field(table).grid;
    
    for (let field of fields) {
        grid.fields_map[field].hidden = 1;
    }
    
    grid.visible_columns = undefined;
    grid.setup_visible_columns();
    
    grid.header_row.wrapper.remove();
    delete grid.header_row;
    grid.make_head();
    
    for (let row of grid.grid_rows) {
        if (row.open_form_button) {
            row.open_form_button.parent().remove();
            delete row.open_form_button;
        }
        
        for (let field in row.columns) {
            if (row.columns[field] !== undefined) {
                row.columns[field].remove();
            }
        }
        delete row.columns;
        row.columns = [];
        row.render_row();
    }
    
}
