- **-l/--columns <colNum\>** :
specify the number of columns in the super table. If both this parameter and `-b/--data-type` is set, the final result number of columns is the greater of the two. If the number specified by this parameter is greater than the number of columns specified by `-b/--data-type`, the unspecified column type defaults to INT, for example: `-l 5 -b float,double`, then the final column is `FLOAT,DOUBLE,INT,INT,INT`. If the number of columns specified is less than or equal to the number of columns specified by `-b/--data-type`, then the result is the column and type specified by `-b/--data-type`, e.g.: `-l 3 -b float,double,float,bigint`. The last column is `FLOAT,DOUBLE, FLOAT,BIGINT`.
- **-L/--partial-col-num <colNum\> ** :
Specify first numbers of columns has data. Rest of columns' data are NULL. Default is all columns have data.
- **-A/--tag-type <tagType\>** :
The tag column type of the super table. nchar and binary types can both set the length, for example:

超级表的数据列的总数量。如果同时设置了该参数和 `-b/--data-type`,则最后的结果列数为两者取大。如果本参数指定的数量大于 `-b/--data-type` 指定的列数,则未指定的列类型默认为 INT, 例如: `-l 5 -b float,double`, 那么最后的列为 `FLOAT,DOUBLE,INT,INT,INT`。如果 columns 指定的数量小于或等于 `-b/--data-type` 指定的列数,则结果为 `-b/--data-type` 指定的列和类型,例如: `-l 3 -b float,double,float,bigint`,那么最后的列为 `FLOAT,DOUBLE,FLOAT,BIGINT`

指定某些列写入数据,其他列数据为 NULL。默认所有列都写入数据。
