1. A method of processing video data, comprising:
determining, based on a dimension of a first video block, an enabling or disabling of a pruning process for a table updating process of one or multiple tables, wherein, in response to the dimension of the first video block being W×H with W≥T0 or H≥T1, the pruning process is disabled, wherein W and H represent a width and height of the first video block, respectively, wherein T0 and T1 are integers, wherein the one or multiple tables are used for constructing a candidate list, and wherein the one or multiple tables are history-based motion vector prediction (HMVP) tables;
updating the one or multiple tables based on the determining and motion information of the first video block; and
performing, subsequent to the updating, a conversion between a subsequent video block of a video and a bitstream of the subsequent video block based on the one or multiple tables,
wherein in response to the dimension of the first video block being 4×4, the pruning process is disabled, and
wherein the updating the one or multiple tables comprises:
refraining from inserting (a) the motion information of the first video block or (b) motion information that is derived from the motion information of the first video block into HMVP table when the pruning process is disabled for the HMVP table updating.
