How to handle null data values

[inver8]

I fetching data which may contain null values, and I need to display them in table as some placeholder
e.g.

[
        {
            "pk": 266,
            "num": "266"
        },
        {
            "pk": 265,
            "num": "265"
        },
        null,
        null,
        {
            "pk": 262,
            "num": "262"
        }
]

But when i pass such data in useMaterialReactTable i got error:

Cannot read properties of undefined (reading 'id')
TypeError: Cannot read properties of undefined (reading 'id')
