Hi kalyanasundaram,
Thank you for your update.
Regarding the issue "How to show the Header automatically without click the Double click to show white space", we have posted the response for this issue through the forum 96116.
Regarding the issue "How to remove the empty paragraphs between the tables or between paragraphs", we have two internal boolean properties of paragraph format named "SpacingAfterAuto" and "SpacingBeforeAuto". We need to disable these properties to set "BeforeSpacing" and "AfterSpacing" properties. Without disabling these properties, BeforeSpacing and AfterSpacing is set to "Auto" instead of the specified value. This causes extra spaces issue. To fix this issue internal boolean properties(SpacingAfterAuto and SpacingBeforeAuto ) must be changed to public properties.
