Module is an universal tool for making table for which is no module. As auser you can:
Usually are used all rows obtained from database. Choosing can reduce the number of rows which should be added. This allows you to create a table by FTF TAGs containing only FTF's and not STF. You can create a table of caches with terrain over 4, under 3 and much more...
If the number of rows has to be reduced this way, you have to choose the right operator to comapare and enter the value you want.
Implicitly is used the operator anything, which means the value is ignored and all rows are shown. Mathematical operators are clear, but you have to be careful while choosing text or numeric comparison. Text comaprison means you have to put the value between apostrophes ('value').
Database operators IN, NOT IN and BETWEEN work with more than one value it's neccessary put the values between apostrophes and separate them using comma (i.e. IN: 'FTF','STF').
Operator LIKE compares the value with mask which can contain wildcard characters _ and %. As an example we can use searching for caches with FTF tags: '%FTF%'. This will use only caches having FTF in tag value (i.e. coFTF).
Most tables contain column with count of something (i.e. the number of found caches of each type). Checkbox Counting defines, which column is used for counting percentage and histograms. For these columns MUST be defined the column with counts, otherwise the module will crash - it will have no idea what it has to count.
Although the module looks like it's universl, there's no possibility to make it really like that. There's too much variability in columns and their contents (especially TAGs) and this brings us many complications for automatisation. That's why sometimes these tables won't work properly or at all.
If you can't use this module, you'll have to make your own SQL command (or ask someone to do it for you) and use SQLTable module.
You can sice define, there's a numeric content in column and use it for sorting, but you can't define there a date or time a sort by them. Sorting by found date i OK, but if there will be a date in TAG, it's neccessary to use the format YYYYMMDD. This time there's no other way to make it.
