#### disable column|row \<name1\> \<name2\> ...
Disable table outputs. If the input file has no row or column names, use inbuild names `R<id>` and `C<id>` to select the rows and columns.
#### insert row|col [\<new-name\>] [\<insert-name\>]
Insert a new row or column. The new row or column will be attached to the end of the table by default. A `new-name` can be provided if the user wants to rename the new row or column. Provide the `insert-name` to insert the new row or column at the specified row or column. The remaining columns or rows will be moved one step right or down accordingly. If the input file has no row or column names, use inbuild names `R<id>` and `C<id>` to select the rows and columns.
#### type row|col int|float|string \<name\>
Set the data type of a row or column. If the input file has no row or column names, use inbuild names `R<id>` and `C<id>` to select the rows and columns.
