Comments:
Hi @nileshkokane01, thanks for your PR. Could you add a check to verify pixel values are created it in the exact same way as the original one by adding TableTransformerImageProcessor to the [conversion script](https://github.com/huggingface/transformers/blob/main/src/transformers/models/table_transformer/convert_table_transformer_to_hf_no_timm.py)?

Ideally it could look like this https://github.com/huggingface/transformers/blob/539ed75d501f9af87b28dc0325b8d2f62b791cd9/src/transformers/models/dinov2/convert_dinov2_to_hf.py#L220
