hey guys, im trying t render a table on to a dash page,  
the table renders perfectly but a few seconds later it crashes saying:  
“Failed to execute ‘querySelector’ on ‘Element’: ‘td[data-dash-column=“AirSpeed 2900  
40+40MHz  
n48  
Numerology=1,SCS=30Khz”][data-dash-row=“0”]:not(.phantom-cell)’ is not a valid selector”  
anyone knows what this is and how come it successfully renders and only then disappears?

Hello @drgitt,

Welcome to the community!

It is really hard to say what is going on without a little bit more detail.

Could you please post an MRE?

Btw, I found that the solution was to not have qoutes " within the header of the datatable.
