Hi @Zarca,
1. In any particular language?
2. Arrow is a columnar format. Thus, it is already formatted like you wrote.
If you mean is the transpose (i.e. `array[i]` corresponds to an array on which
entry is the value of a column), then AFAIK there is no way without a scan i.e.
```
for row in rows {
for column in table.columns() {
value = column[row]
}
}
```
as, like I mentioned, Arrow memory alignment is at the column level, no row
level.
