Search for a cell value in a org.eclipse.swt.widgets.Table control.

Never used this type of table myself.

But it appears to be an SWT object?

In which case, this: https://support.smartbear.com/testcomplete/docs/reference/test-objects/members/window-and-process/swtobject-method.html

... looks like it might be a good starting point?

try this objTable.getValueAt(rownum,colnum), you might get the cell value.
