Thanks MorningZ, i've check your code and there is something i do not understand... as i'm still rookie to jQuery i'm maybe asking a stupid question , so in this case sorry. when you call the following function
Grid_Colunns_Resize($("#frm_table, #data_grid")); in fact $("#frm_table, #data_grid") correspond to an array of ID, am i right ? in your code you resize the width of column header not the width of cell column. will it make any changes in your code ? because basically there is not TH in the second table, but tbody, tr,td. one thing that i do not understand in find command...(maybe i'm stupid :-( ) when you write .find('tr,td') is it the same as .find('tr').find('td') ? i did not find anything in the documentation even if in books. most of the time they use .find('tr').find('td') or .find('tr td') thanks for feedback.
