Test whether an object is a valid TabularRow object:
TabularRow[{1, 2, 3, 4}]TabularRowQ[%]Test whether an object is a valid TabularRow object:
TabularRow[RandomDate[3]]TabularRowQ[%]Test whether an object is a valid TabularRow object:
TabularRow[Alphabet[]]TabularRowQ[%]Scope (4)
Validate a TabularRow object with named entries:
TabularRow[<|"c1" -> "a", "c2" -> x, "c3" -> 7|>]TabularRowQ[%]Validate a TabularRow object with anonymous entries:
TabularRow[{"a", x, 7}]TabularRowQ[%]TabularRowQ gives False for anything that is not a TabularRow object:
TabularRowQ[x]TabularRowQ[ListPlot[{1, 2, 3}]]TabularRowQ[TabularColumn[{1, 2, 3}]]TabularRow objects can be empty:
TabularRow[{}]TabularRowQ[%]Applications (2)
Check if a part of a Tabular object is a valid TabularRow:
tab = Tabular[{{"a", x, 7}, {"b", y, 9}}, {"c1", "c2", "c3"}]tab[1]//TabularRowQTest if given data admits given types in TabularRow:
data = {1, "cat", True};
types = {"Integer", "String", "InertExpression"};TabularRow[data, <|"ColumnTypes" -> types|>]//TabularRowQProperties & Relations (2)
TabularRowQ checks validity of a TabularRow object:
TabularRowQ[TabularRow[Range[5]]]A TabularColumn object with the same data is not a valid tabular row:
TabularRowQ[TabularColumn[Range[5]]]Use TabularColumnQ to validate TabularColumn objects:
TabularColumnQ[TabularColumn[Range[5]]]A Tabular object containing a single row is not a valid tabular row:
tab = Tabular[{{1, 2}}, {"col1", "col2"}]TabularRowQ[tab]Its row is a valid TabularRow object:
tab[[1]]TabularRowQ[%]Use TabularQ to validate Tabular objects:
