Description

Blueprint function library for querying UDataTable assets — row lookups, existence checks, and column/row name introspection — plus editor-only CSV/JSON import and export.

Caveats & Gotchas

• Most import/export members (FillDataTableFromCSVString/File, FillDataTableFromJSONString/File, AddDataTableRow, RemoveDataTableRow, ExportDataTableToCSV/JSON) are wrapped in #if WITH_EDITOR and are compiled out of packaged/runtime builds entirely.
• GetDataTableRowFromName is a CustomThunk wildcard function bound to the "Get Data Table Row" Blueprint node; its OutRow struct type is inferred from the wired pin, not from the raw C++ signature.

Access	Type	Name	Description
public	function	UDataTableFunctionLibrary::DoesDataTableRowExist	Returns whether Table contains a row named RowName.
public	function	UDataTableFunctionLibrary::GetDataTableRowFromName	Looks up the row named RowName in Table and copies its data into OutRow, returning whether the row was found.
public	function	UDataTableFunctionLibrary::GetDataTableRowNames	Fills OutRowNames with the name of every row in Table, in the table's internal storage order.
public	function	UDataTableFunctionLibrary::EvaluateCurveTableRow	Evaluates the curve stored in RowName of CurveTable at InXY and returns the interpolated Y value, branching based on whether the row was found.
public	function	UDataTableFunctionLibrary::GetDataTableColumnAsString	Exports every row's value for a single column as an array of strings, in row order, excluding the row name.
public	function	UDataTableFunctionLibrary::GetDataTableColumnExportNames	Fills OutExportColumnNames with the friendly export name of each column, matching the header row of a CSV/JSON export of Table.
public	function	UDataTableFunctionLibrary::GetDataTableColumnNameFromExportName	Looks up the raw property name of a column given its friendly export name, returning whether a match was found.
public	function	UDataTableFunctionLibrary::GetDataTableColumnNames	Fills OutColumnNames with the raw property name of every column in Table's row struct.
public	function	UDataTableFunctionLibrary::GetDataTableRowStruct	Returns the row struct type used by Table, or null if the table doesn't have one set.
