How to find total number of rows and columns in a table in Selenium

We can use below XPATH expressions to find count of rows and columns in a table.

1. //table//th  - Find total number of columns in a table. Note that this will only work if all columns are marked using th tag
2. //table//tr - Find total number of rows in a table.
3. //table//tr[1]//td - Find total number of TD tags inside a given table row.
