hi paramvir：
Using pqgrid in react, if you use the on-demand loading method, cVirtual.setSBDim(); this method will have a loading delay problem, causing the getSBWd method to return pq.cVirtual.SBDIM as undefined, so in autoFitCols wdCont = NaN (wdCont = dims.wdCenter-sbWidth), causing autoFit to fail
