Can I make a dash table input into a callback?

Hi @xiaodai and welcome to the Dash Community! :slightly_smiling_face:

The properties of the DataTable can absolutely be used as inputs to a callback. :confetti_ball: You just need to use a valid table property - such as “data” or “columns” or one of the many other many table properties. ('table1' looks like it might be an id ?)

If you post a little more code - like a minimal example that will reproduce the error, it will be easier to help. See more information here: How to Get your Questions Answered on the Plotly Forum
