A Data frame is a two-dimensional data structure, i.e., data is aligned in a tabular fashion in rows and columns. A SQL Server table is a slightly different structure, where rows and columns are not equivalent and interchangeable. rotate the table by 90 degree to turn all rows into columns and vice versa. DISCLAIMER: It is import that you set USE_NGROK to true when using D-Tale within this service.
