When you put data in a table, filter controls are added on it's own on the table headers.
Step-by-step explanation:
Every column that you are working on has a column header. When you want to filter a particular column, we have to select the column header of that column. Then the next step is to unselect the option of selecting all the columns and after this option is unselected, we can select the boxes of our own choice which we want to be shown and worked upon. Then option of OK is to be selected and then the arrow of column header gets changed to a filter icon.
