    """
    Write a pandas DataFrame to a TsFile by inferring the table schema from the DataFrame.
    This function automatically infers the table schema based on the DataFrame's column
    names and data types, then writes the data to a TsFile.
    Parameters
    ----------
    dataframe : pd.DataFrame
        The pandas DataFrame to write to TsFile.
        - If a 'time' column (case-insensitive) exists, it will be used as the time column.
        - Otherwise, the DataFrame index will be used as timestamps.
        - All other columns will be treated as data columns.
    file_path : str
        Path to the TsFile to write. Will be created if it doesn't exist.
    table_name : Optional[str], default None
        Name of the table. If None, defaults to "table".
    time_column : Optional[str], default None
        Name of the time column. If None, will look for a column named 'time' (case-insensitive),
        or use the DataFrame index if no 'time' column is found.
    tag_column : Optional[list[str]], default None
        List of column names to be treated as TAG columns. All other columns will be FIELD columns.
        If None, all columns are treated as FIELD columns.
    Returns
    -------
    None
    Raises
    ------
    ValueError
        If the DataFrame is empty or has no data columns.

If you skip the time column, it will be missing when the file is loaded into IoTDB.

The name of the time column should be prevserved.
