No, there is not. The "Tables" objects is how you interact with Tables in script code and keyword tests. Unfortunately, this object has no methods or properties on it to add them dynamically.
This is one of the primary disadvantages to checkpoints in TC with one exception: that you need to create your baselines for comparison manually rather than dynamically in script. The exception is the "Objects"... you can add those dynamically in script using the Objects.Add method to add an onscreen object and it's properties to the Objects stores.
Is there a reason why you need to do this via script? It seems that, if you have the data in your Excel, you already have your baseline. Write code to iterate through the onscreen table and compare it to rows and columns in your excel spreadsheet to compare values. No need to have them as "tables" in TestComplete... Excel, essentially, acts as your tables.
