1) create required parameters in the main report by right clicking on the parameters section of main report------> add parameter-------->set the properties (data type) of newly added parameter to your desired one.
2) create equivalent parameters in the table/List's data source's parameters section exactly as in step 1.
3) from report explorer, right click on the table and click on Edit Table DataSet ------> clickthe parameters button----------->Click add ---------->Choose the parameter (which you created in the dataset's parameter section in step 1) from upper combo (i.e. Dataset parameter name) ------> then click on lower button (i.e.) assign value expression i.e. the params which you added in step 1.
