How to retrieve table data from a table which spans multiple pages of a document in a single table.

Question

I have followed the video you posted and have mapped a few rows from each page of the table which spans multiple pages. When the training is complete and i test, the data returned is only from the rows which i mapped.

1. See below:

The Test return perfectly read the 7 mapped fields but not all in the table.

I mapped the headers in the manual table like the video and highlighted and inserted the sample data.

Please can you let me know how i can get the full table from all pages, sometimes 8 pages where i specify the headers? Do i need to map a version of the pdf with 8 pages? what if there is nine.

Everything is very clear and successful other than this point of getting data from multiple pages.

Thank you Support in advance

Hello @Daniel Lincoln - Trimco UK , Thanks for using Microsoft Q&A Platform.

Tabular fields in Document intelligence support cross page tables by default. To label a table that spans multiple pages, you need to label each row of the table across the different pages in a single table. As a best practice, it's recommended to ensure that your dataset contains a few samples of the expected variations. Please follow this documentation: https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/concept-custom-label?view=doc-intel-4.0.0#tabular-fields

Multi page tables: When tables span multiple pages, label a single table. Add documents to the training dataset with the expected variations represented—documents with the table on a single page only and documents with the table spanning two or more pages with all the rows labeled. https://learn.microsoft.com/en-us/azure/ai-services/document-intelligence/concept-custom-label?view=doc-intel-4.0.0#create-a-balanced-dataset

In this kind of cross-page table scenarios try with Custom Neural model for best results.

I hope this helps.
