使用jQuery过滤掉生成的表的行的问题

I'm trying to filter out rows of an HTML table based on user input from a dropdown menu. My idea is to remove the rows if the first column of the first row is not equal to the value of the drop down menu. However the only thing I've been able to make it do is either just remove the first column, remove everything, or everything except the first column, depending on how I've messed with the jquery function. I'm sure it's something simple but I can't figure it out. The code I'm using is below: Jquert function:I'm trying to filter out rows of an HTML table
