Merging & Joining

Merge DataFrames

TablrDataFrame* tablr_dataframe_merge(const TablrDataFrame* left, const TablrDataFrame* right, 
                                       const char* on, TablrJoinType join_type);

Merge two dataframes on a common column.

Join Types: - TABLR_JOIN_INNER - Inner join (intersection) - TABLR_JOIN_LEFT - Left outer join - TABLR_JOIN_RIGHT - Right outer join - TABLR_JOIN_OUTER - Full outer join (union)

Example:

TablrDataFrame* merged = tablr_dataframe_merge(df1, df2, "ID", TABLR_JOIN_INNER);

Concatenate DataFrames

TablrDataFrame* tablr_dataframe_concat(const TablrDataFrame** dfs, size_t count);

Concatenate multiple dataframes vertically.

Example:

TablrDataFrame* dfs[] = {df1, df2, df3};
TablrDataFrame* combined = tablr_dataframe_concat(dfs, 3);
