Description
Hi Daniel,
I've been watching your p5.js tutorial series. It's excellent. Thank you!
I'm trying to combine the dropzone you demonstrate in 8.15 with the tabular data functionality shown in 13.5. I'm stuck so I came here to see if anyone else is having the same issue. I can't find any threads with the same question though.
I am having a problem as the table I get from the file is showing an empty array in the console:
_p5.Table {columns: Array(0), rows: Array(0)}
columns
:
(2) ["Destination", "Price"]
rows
:
(2421) [p5.TableRow, p5.TableRow …]
__proto__
:
Object_
_undefined_
This means I cannot access the data. Everything just returns undefined. How can I fix this so that the array shows {columns: Array(2), rows: Array(2421)} as expected?
My code:
function gotFile(myfile){
vox2 = loadTable(myfile.data,"csv", "header");
console.log(vox2);
console.log(vox2[0]);
}
Any help you can offer would be very much appreciated.

Research direction
Start by reproducing the reported loadTable behavior using the dropzone example from tutorial 8.15, the table example from 13.5, and the supplied gotFile code. Compare the p5.Table object and CSV-loading path; done means the issue has a confirmed cause and a documented fix.
