The error MultipleCompilationErrorsException means you have defined the same variable more than once. Somewhere in your code, you likely copied and pasted the variables, Table, rows_table and Columns_row. What you need to do is remove the definition from in front of the variables. You can leave the definition in front of the very first one in your code, then remove all others. As an example, keep your definition in the first instance:
WebElement Table = driver.findElement(...)
but any other use of the same variable, you just use:
Table = driver.findElement(...)
Same goes for the others listed in your error message.
