The first rows above tables can be used to change table auto-filters.
To change the auto-filter, just enter a value in the cell above the table column.
The following substitution characters are available: ?, *, >, <, <>.
For example, the '<>*AA*' value filters all the rows except the rows which contain 'AA'.
To turn off a current column auto-filter, just clear the value in the cell over the table column.
This feature can be turned on or off in the Options menu.
In the example on the screenshot, the rows with the sum above 100000 and the 'Inc' value in the company names are filtered.
