The error message is very descriptive, you've given it a td when it expects a select (rightly so).
So here:
Select CompanyOptions = new Select(_driver.findElement(By.xpath(".//*[#id='company._idCell']")));
You need to change this to give it the select:
Select CompanyOptions = new Select(_driver.findElement(By.id("inputSelect")));
