Yes, the fields are normal Palm OS fields... you need to set the field

Yes.
We cover this in our book (Palm OS Programming For Dummies, due out in
July) Here's the basic idea:
1) when you load the form with the table, you need to establish a Load
Data procedure for the column containing the field:
TblSetLoadDataProcedure(table, 3, DescriptionBlock); // assumes column
3 is the desired column
2) Then you code the Load Data procedure (in this example,
DescriptionBlock())
static Err DescriptionBlock (VoidPtr table,
Word row, Word column, Boolean editable,
VoidHand *dataH, WordPtr dataOffset,
WordPtr dataSize, FieldPtr fld) {
FieldAttrType attr;
// Set table field attributes
FldGetAttributes (fld, &attr);
attr.dynamicSize = 0; // don't resize as text is entered
FldSetAttributes(fld, &attr);
return 0;
}
That will do it ;)
