Further enhance Table tool

[Haokun]

There is duplicated action in the table tool to force the user decide the decimal places.

In the normal situation, all the data preparation process has been completed prior to the Table tool, we just want to leverage on this tool to format the header or incorporate conditional formatting. However, once the Table tool is connected and we have to re-configure the decimal places for all the numeric columns, the column names will be varied from year to year and it brings additional manual intervention to the workflow.

We recommend to provide flexibility for us to take the original upstream data source without changing the underlying data set.
