an unmanaged delta table is dropped and the real data still there. Now I'm trying to rebuild it, but don't know the schema. So, I tried: val myTable = DeltaTable.forPath("myPath"). But how can I get the data or schema out from myTable?
Thanks!

@andrew li
df = spark.read.format("delta").load("/file_path")
df.printSchema()
