Provide examples on how to implement tables for different langauge

[BhupenderAgarwal24]

I was going through the available documentation on how to implement step tables in Gauge but there is very limited documentation available and it just talks about how one can call tables in step implementation but it'll be nice to elaborate the example and demonstrate the implementation of a sample table.

Also, I don't see the list of methods applicable to the table object. It'll be nice to add the same. However, the workaround is to use table.rows.methods to get the list of methods.
