Hello Prabu,
Please remember that whenever you design a table in the layout, you should not drag the table directly from DATA VIEW. Instead you should drag only the DATA part of the Table since doing this way keeps the DATA part in a sub form. Then you wrap a parent sub form and bind it with the table if you want to. Sub forms will give you a lot of flexibility for defining run time attributes.
Now you can follow the detailed steps given below to design a table in an efficient manner and also resolve the Overflow issue of the field.
DATA sub form
Step 1) In layout editor you will be able to see a table in data view tab.
Step 2) Don't drag the whole table. Instead, drag only the data part of the Table in the content area sub form in the design view(body page)tab.
Step 3) Select this DATA sub form and in the object palette give content as flowed and Uncheck the "Allow Page breaks within content".
Step 4) In Flow direction, give Western text.
Step 5) In Binding tab,Check the "Repeat sub form for each data item".
Table sub form
Step 1) Wrap the DATA sub form in a parent sub form. So this parent sub form will be a Table sub form.
Step 2) Click on the parent sub form under which the DATA sub form is available. Select this parent sub form and in the object palette give content as flowed. In Flow direction,giveTop to bottom. And check the"Allow Page breaks within content". In place give Following previous and in After give Continue filling Parent.
Step 3) If needed, you can do the binding in the Binding section by selecting the internal table name.
