Dynamically change cell properties in a table

Question

Hi,
I have read all forum posts about changing table cell properties, but I can't find the solution to my problem.
I have a table that derives its structure from a table which is the output of an RFC.
The rows are provided by the model.
When displaying the result of the RFC call, I want to add a colored row between certain sections with totals of that particular section.
I managed to add the row in the appropriate place, however I cannot change the color of this row (or even better: the particular cell).
Can anyone tell me how to proceed? And what property determines backgroundcolor of a tablecell? TextViewSemanticColor determines the text color, I want to change the background color.
Here is a fragment from my wdDoModifyView:
i=0;
IPrivateResultView.IEp_OpportunitiesNode node = wdContext.nodeEp_Opportunities();
while (i<node.size()) {
     total1 += <some value>;
     total2 += <some value>;
     if (<start of new section>) {
          IPrivateResultView.IEp_OpportunitiesElement el = (IPrivateResultView.IEp_OpportunitiesElement) node.createElement(new Zopportunities());
          el.setAttributeValue("Exp_Revenue", new BigDecimal(total1));
          el.setAttributeValue("Chancevalue", new BigDecimal(total2));
//     totals row is added here:                    
          node.addElement(i, el);
//     how can I make this work for background color?
          el.node().getNodeInfo().addAttribute("TextViewSemanticColor", "ddic:com.sap.ide.webdynpro.uielementdefinitions.TextViewSemanticColor");
          el.setAttributeValue("TextViewSemanticColor", WDTextViewSemanticColor.NEGATIVE);
          total1 = 0;
          total2 = 0;
     i++;
Thanks in advance,
Roelof

Hello Knibbe,
One can play with the readOnly of table cell editor (Input Field) to acheive the expected result.
Let us take a specific case where your table has four columns say col1, col2, col3, col4 and each of these columns have Input field as the table cell editor.
Then depending upon the condition specified below choose your option.
<u>If you have bound the table to the model node</u>
1. Create a new value node and create a bolean value attribute under it.
2. Set the cardinality of the value node to 1:1 and singleton to false.
3. Bind this attribute to the Table cell editor <b>(Inputfield)</b> in col1, col2, col3 and col4.
4. set the value of this attribute to TRUE when the table gets filled up initially i.e for the elements/rows in which you want to display the total, as per your requirement.
5. set the value of this attribute to FALSE for the other rows where you want the user to edit the data.
<u>If you have bound the table to a value node</u>
1. Create a value attribute of type boolean under the value node and follow the ONLY the steps 3, 4 and 5
Please reward appropriate points.
