Data Table column shows empty even though data exists (refresh/display issue)

Hi everyone,

I'm experiencing a strange issue in Power Apps (both in the Teams version and the web version):

One of the columns in my Data Table appears empty, even though the data clearly exists in the source (Dataverse in my case).

Here's what I’ve observed :

The records are correctly filled in Dataverse.

If I delete the Data Table and re-add it with the exact same source, the column displays as expected. But if I refresh the app/page, the column becomes empty again.

There are no filters or formulas applied , the items property directly references the data source.

I’ve tried using refresh() and also storing the data in a collection, same issue

This only affects one or a few columns; the rest display fine.

It feels like Power Apps is not refreshing the schema or column bindings correctly unless I manually recreate the Data Table.

Has anyone encountered this issue before ?

Thanks in advance!

I’ve attached two screenshots to this post :

One before deleting and re-adding the Data Table (where "Statut validation" is empty),

One after re-adding it (where everything displays correctly).

@jinfanti Hi,

Did you use the Classic table or the new one ?

Those columns, are same data type or different ?

can you add a label to display it ? for example :

Table1.Selected.'Account Name' ( choose the not displayed column)

Hi!:)

Thanks for your reply!

Yes, I'm using the new Data Table control, not the classic one.

The columns have different data types, "Statut validation" is a Choice field, but other Choice columns display correctly.

I also tried displaying the value in a label using something like Table4_6.Selected.'Statut validation'.
The label shows the correct data, even when the column appears empty in the Data Table.

So the data is definitely there, it's just not rendering in the Data Table until I delete and re-add it.

@jinfanti Hi,

Sounds like a bug ( not stable)

some others work around you may want to try if you keep using the new control.

Other options:

Reduce the height of the table , like 600 px.

Change the type to Yes/No, for example Column name = IsValidated, value =1,0, Label = Yes/No.

Use default value ( not None).

Use customized value, not like 214,789,123

hope that help a little bit.

Hi

Thanks again for your suggestions!

Unfortunately, I can’t change the column type to Yes/No because this is part of a project with strict requirements and the data model is imposed. So the "Statut validation" column must remain a Choice field with specific options.

Also, I tried reducing the height of the Data Table (to around 600px or less) but unfortunately, it didn’t fix the issue. The column still appears empty until I delete and re-add the control.

The “Statut validation” column is a Choice field just like my other Choice columns, which work fine and display correctly.

@jinfanti Hi,

Hardly to reproduce it.

I still doubt the choice value ( if not a bug of the control).

If you have a separated customized publisher, from there you can find the suggested 'Choice value prefix'.

Also, please use Dev tool of the browser to monitor the data loading if you can find anything special .

Or combine live monitor.

Hello

I removed the numeric values (0/1) from the Choice column and switched to using the default text values provided by Dataverse, but the issue remains exactly the same. The column still appears empty in the Data Table unless I delete and re-add the control. When I publish the app, the problem persists regardless of where I open it — whether in Power Apps or Teams.

Thanks again for your time and guidance!
