I have been successfully using this very useful package, and until recently could implement hyperlinks in a column with the code:
gb.configure_column("ISSUE", headerName="ISSUE", cellRenderer=JsCode('''function(params) {return '<a href="https://thebcd.co.uk/issue_' + params.value + '" target="_blank">'+ params.value+'</a>'}'''), width=300)
which would result in a hyperlink to an address related to the cell value.
On editing a different part of of my app, I now find that instead of creating a hyperlink to the address, the html text is written to the screen instead:
<a href="https://thebcd.co.uk/issue_1" target="_blank">1</a>
rather than the hyperlink from the cell value 1 to the address. Any help appreciated.
