Empty Table Creator

Creates an empty file: simply lines and RowKeys.

Options

Number: The number of rows to create in the empty table. Only row keys will be generated, no actual data columns are added to the table.
Prefix: The prefix used for generating row key identifiers. Each row key will consist of this prefix followed by a unique number (e.g., 'Row1', 'Row2', etc.).
Skip: A random number of row keys between 0 and this value will be skipped during generation. This creates gaps in the row key numbering sequence. If the number is less than 0, no keys are skipped.
Use seed: When enabled, the row key generation will use a fixed seed value, making the randomization reproducible across multiple executions. When disabled, each execution will produce different random row key sequences.
Random seed: The seed value used for random number generation. Use the same seed to get identical row key generation results across multiple executions. You can enter a custom value or use the random seed generation button below.
Draw seed: Generate a random seed and set it in the Random seed input above for reproducible runs.
