     1. If in a block of type Table_Contents_Info a table consists out of only one IVI, both dimensions, Column_CSI and Row_CSI must be specified in the TDI used.
     2. If in a block of type Table_Contents_Info a table consists out of multiple IVIs, either Column_CSI or Row_CSI must be specified.
     3. Large dimensions, e.g. number of time steps, can only be processed as Row_CSI, because the maximum number of columns is limited.

  1. Name: short name.
     1. The folowing file(s) is (are) created for this type of table:

     2. In case several TCI blocks are specified, Name must be unique.
  2. TDI: Valid Name from block Table_Design_Info
     1. Will be used to design the table.
