PennController.GetTable( tablename ).filter( "column" , "match" )

or PennController.GetTable( tablename ).filter( "column" , /match/ )

or PennController.GetTable( tablename ).filter( function )

Returns a filtered version of the table, containing only rows whose specified column’s value is a match.

If you use a string then the column’s value must match the text exactly. Alternatively, you can use a regular expression to test the column’s value. You can also use a function that will take each row as an argument and should return true to keep the row or false to exclude it.

You can use several filters in chain.


[js highlight=”3,4″ try=”data”]
GetTable( “spreadsheet.csv” )
.filter( row => row.Item > 0 ) // ‘Item’ should be greater than 0, and
.filter( “ButtonText” , /second/ ) // ‘ButtonText’ should contain ‘second’
row => newTrial( “button trial” ,
newButton(“test button”, row.ButtonText)
.log( “Item” , row.Item )
.log( “Text” , row.ButtonText )

Generates only one trial from a subset of the table spreadsheet.csv: first we only consider rows where the value in the Item column is a number greater than 0 (this is practically ineffective, for both rows in spreadsheet.csv already satisfy this condition) and we further consider only rows among those rows where the value of the ButtonText column is a text containing the string second (only the second row satisfies this condition).
