Hi @PVA ,

tableDataTypes.fsm

You can convert the table it to a treenode and then use the 'dataType' property of the treenode class.

See Jason's answer above for an updated solution.

treenode DataNode = Table("GlobalTable2").as(treenode);
print(DataNode.dataType); // tests to see current data type
DataNode.dataType = DATATYPE_NUMBER ; // set data type to Number
print(DataNode.dataType); // test to confirm new datatype

The datatype macros can be found here

Note: changing the datatype to certain datatypes may change your table. To reset it, simply run the code to set back to the original datatype.

This post may also be helpful in testing the datatype of table nodes

Hi Carter,

Thank you for your answer. But it hasn't completely solved my problem. I'm trying to duplicate a bundle table and convert the datatype from bundle to integer. I'm attaching the model FYR.

Thank you.tabledatatypes.fsm

You are trying to make the table a bundle type or making each cell type as bundle.

I'm assuming you want to change the individual table cells from arrays to numbers? (A bundle is a different data structure for the entire table)

For that you can either use Table.setSize() and overwrite the previous values. But this will also remove any row and column headers.

Alternatively you can loop through all cells and change their data type individually.

Table table2 = Table("GlobalTable2");

// This also resets headers
table2.setSize(table2.numRows, table2.numCols, DATATYPE_NUMBER, 1);

// Loop through cells instead
for(int row = 1; row <= table2.numRows; row++)
{
    for(int col = 1; col <= table2.numCols; col++)
    {
        table2.cell(row, col).dataType = DATATYPE_NUMBER;
    }
}

You can't change a table (a structure of related data values stored as a bundle or nested treenodes) to a single number and retain the data.

When you have bundle data in a treenode table's cell, you can simply overwrite the cell data with a new variant:

Table("GlobalTable2").cell(2,1).value=6

If anyone finding this post wishes to toggle between treenode-based and bundle table types here's some updated code showing an example data node that is a cell within a global table (first line - this was the case in the orginal poster's model)

treenode data=Table("GlobalTable2").cell(4,1);   //Global table data or other data node
int isGlobalTable=classobject(data.up)==library().find("?GlobalTable");
treenode newData;
if(getdatatype(data) != DATATYPE_BUNDLE) {
    newData = nodeinsertafter(data);
    nodeadddata(newData, DATATYPE_BUNDLE);
} 
else if (isGlobalTable) //Copy from the library so we get our TableHeader node
   newData = createcopy(library().find("?GlobalTable>variables/data"), data.up);
else {   //just a node somewhere
     newData = nodeinsertafter(data);
     newData.value="<Treenode Table>";   // so a user can see the node contains table structure
 }
data.as(Table).cloneTo(newData.as(Table));
createcopy(newData,data,1,0,0,1);  // this preserves any pointers to the table that already existed in the model
destroyobject(newData);
