datafusion-cli regression: explain plan output looks bad (error rendering multi-lines) #14947
Description
Describe the bug
Explain plans look good in DataFusion 45:
DataFusion CLI v45.0.0
> create table foo(x int, y int) as values (1,2), (3,4);
0 row(s) fetched.
Elapsed 0.007 seconds.
> explain select * from foo where x = 4;
+---------------+---------------------------------------------------+
| plan_type | plan |
+---------------+---------------------------------------------------+
| logical_plan | Filter: foo.x = Int32(4) |
| | TableScan: foo projection=[x, y] |
| physical_plan | CoalesceBatchesExec: target_batch_size=8192 |
| | FilterExec: x@0 = 4 |
| | MemoryExec: partitions=1, partition_sizes=[1] |
| | |
+---------------+---------------------------------------------------+
2 row(s) fetched.
Elapsed 0.005 seconds.
However, they look really bad on main (aka pre-release DataFusion 46):
> create table foo(x int, y int) as values (1,2), (3,4);
0 row(s) fetched.
Elapsed 0.018 seconds.
> explain select * from foo where x = 4;

TableScan: foo projection=[x, y] |
| physical_plan | CoalesceBatchesExec: target_batch_size=8192

DataSourceExec: partitions=1, partition_sizes=[1]

To Reproduce
create table foo(x int, y int) as values (1,2), (3,4);
explain select * from foo where x = 4;Expected behavior
I expect the cells to be correctly rendered like in DataFUsion 45
Additional context
This appears to be another issue introduced by
