AFAIK, there is no way for Arrow to consistently determine the correct
order. In Arrow, columns are allowed to have duplicate names so something like
this would be allowed:
```
tab1 = pa.Table.from_pydict({
"col": [1,2,3,4,5],
"col": [6, 7, 8, 9, 10],
})
tab2 = pa.Table.from_pydict({
"col": [6, 7, 8, 9,10],
"col": [1,2,3,4,5],
})
```
Two tables with different schemas can't be combined. You will need to
normalize the schema in your code (or perhaps pandas) before providing it to
Arrow.
