set_columnstypes
Set the type of certain columns.
Call:
ts_table(iTableDescr,"set_columnstypes",string col1name, string stype1, string col2name, string stype2,...);
or
ts_table(iTableDescr,"set_columnstypes",int col1, string stype1, int col2, string stype2,...);
Here:
col1name, col2name - columns by name, can be inconsistently,
stype1, stype2 - type names ("string", "int", "double", "bool");
col1, col2 - column numbers.
